The run was delightful, and was the commencement of a very pleasant friendship. He saw that his little friend was in no way averse to a violent flirtation, and indeed, he spent nearly the whole of the next morning with her in the garden.

The chauffeur had already disregarded the Parson’s advice, and had fallen desperately in love with her.

As they sat in the garden she told him that her mother was a Roumanian lady, of Bucharest, whose sister had married the enormously wealthy landowner, Prince Charles of Krajova. For the past two years she had lived in Paris, Vienna and Bucharest, with her aunt, and they were now at San Remo to spend the whole winter.

“But,” she added, with a wistful look, “I far prefer England. I was at school at Folkestone, and had a most jolly time there. I was so sorry to leave to come out here.”

“Then you know but little of London?”

“Very little,” she declared. “I know Folkestone better. We used to walk on the Leas every day, or play hockey and tennis. I miss my games so very much,” she added, raising her fine big eyes to his.

At his invitation she walked down to the town and back before luncheon, but not without some hesitation, as perhaps she thought her aunt might not like it. On the Promenade they met his Highness, but he gave them no sign of recognition.

“That gentleman is staying at our hotel,” she remarked after he had passed. “I saw on the list that he is a Mr Tremlett, from London.”

“Yes – I also saw that,” remarked the chauffeur. “Looks a decent kind of fellow.”

“Rather a fop, I think,” she declared. “My aunt, however, is anxious to know him, so if you make his acquaintance, will you please introduce him to us?”

“I’ll be most delighted, of course, Miss Dalrymple,” he said, inwardly congratulating himself upon his good fortune.

And an hour later he wrote a note to the Prince and posted it, telling him of what the girl had said.

While the Parson monopolised the Princess, Garrett spent most of the time in the company of Winifred Dalrymple. That afternoon he took the Parson and the ladies for a run on the car, and that evening, it being Christmas Eve, there was a dance, during which he was on several occasions her partner.

She waltzed splendidly, and Garrett found himself each hour more deeply in love with her. During the dance, he managed to feign to scrape acquaintance with the Prince, and presented him to his dainty little friend, as well as her aunt, whereat the latter at once went out of her way to be most gracious and affable. Already the handsome Tremlett knew most of the ladies in the hotel, as his coming and going always caused a flutter within the hearts of the gentler sex, for he was essentially a ladies’ man. Indeed, to his easy courtly manner towards them was due the great success of his many ingenious schemes.

He would kiss a woman one moment and rifle her jewel-case the next, so utterly unscrupulous was he. He was assuredly a perfect type of the well-bred, audacious young adventurer.

While the dance was proceeding Garrett was standing with Winifred in the hall, when they heard the sound of an arriving motor-car coming up the incline from the road, and going to the door he saw that it was a very fine sixty horse-power “Fiat” limousine. There were no passengers, but the driver was a queer grey-haired, hunchbacked old man. His face was splashed, his grey goat’s-skin coat was muddy, like the car, for it was evident that he had come a long distance.

As he entered the big brilliantly-lit hall, his small black eyes cast a searching look around. Winifred, whom Garrett was at that moment leading back to the ballroom, started quickly. Had she, he wondered, recognised him? If so, why had she started. That she was acquainted with the stranger, and that she did not wish to meet him he quickly saw, for a few moments later she whispered something to the Princess, whose face instantly changed, and the pair pleading fatigue a few minutes later, ascended in the lift to their own apartments.

So curious was the incident, that Garrett determined to ascertain something regarding the queer, wizened-faced old hunchback who acted as chauffeur, but to his surprise when he returned to the hall, he found the car had already left. The little old man in the fur motor-coat had merely called to make inquiry whether a certain German baron was staying in the hotel, and had then left immediately.

He was much puzzled at the marked uneasiness of both the Princess and Winifred at the appearance of the mysterious “sixty.” Indeed, he saw her Highness’s maid descend the stairs half an hour later, evidently in order to gather some facts concerning the movements of the hunchback. Prince and Parson were both playing bridge, therefore Garrett was unable to relate to them what he had seen, so he retired to bed wondering what the truth might really be.

Morning dawned. The Prince and his friend were both down unusually early, walking in the garden, and discussing something very seriously. But its nature they kept from their chauffeur.

The morning he spent with Winifred, who looked very sweet and charming in her white serge gown, white shoes and big black hat. They idled in the garden among the orange groves for an hour, and then walked down to the town and back.

At luncheon a surprise awaited them, for quite close to Garrett sat the little old man, clean and well-dressed, eating his meal and apparently taking no notice of anybody. Yet he saw what effect the man’s presence had produced upon the Princess and her niece, who having taken their seats could not well escape.

Where was the big “sixty”? It was certainly not in the garage at the hotel! And why had the old man returned?

Reviewing all the circumstances, together with what the Prince had explained to him in Dover Street, he found himself utterly puzzled. The whole affair was an enigma. What were the intentions of his ingenious and unscrupulous friends? The Prince had, he recollected, distinctly told him that diamonds were not in the present instance the object of their manoeuvres.

About three o’clock that afternoon he invited the Princess and her pretty niece to go out for a run in the car to Taggia, the road to which first runs along by the sea, and afterwards turns inland up a beautiful fertile valley. They accepted, but both Prince and Parson pleaded other engagements, therefore he took the two ladies alone.

The afternoon was bright and warm, with that blue sky and deep blue sea which is so characteristic of the Riviera, and the run to Taggia was delightful. They had coffee at a clean little osteria – coffee that was not altogether good, but quite passable – and then with Winifred up beside him, Garrett started to run home in the sundown.

They had not gone more than a couple of miles when, of a sudden, almost before he could realise it, Garrett was seized by a contraction of the throat so violent that he could not breathe. He felt choking. The sensation was most unusual, for he broke out into a cold perspiration, and his head beginning to reel, he slowed down and put on the brake, for they were travelling at a brisk pace, but beyond that he remembered absolutely nothing. All he knew was that an excruciating pain shot through his heart, and then in an instant all was blank!

Of only one other thing he had a hazy recollection, and it was this. Just at the moment when he lost consciousness the girl at his side, leant towards him, and took the steering-wheel, saying:

“Let go, you fool! – let go, will you!” her words being followed by a weird peal of laughter.

The darkness was impenetrable. For many hours Garrett had remained oblivious to everything. Yet as he slowly struggled back to consciousness he became aware that his legs were benumbed, and that water was lapping about him. He was lying in a cramped position, so cramped that to move was impossible. He was chilled to the bone. For a full hour he lay half-conscious, and wondering. The pains in his head were awful. He raised his hand, and discovered a nasty wound upon his left temple. Then he at last realised the astounding truth. He was lying upon rocks on the seashore, and it was night! How long he had been there, or how he had come there he had no idea.

That woman’s laughter rang in his ears. It was a laugh of triumph, and caused him to suspect strongly that he had been the victim of feminine treachery. But with what motive?

Was it possible that at Taggia, while he had been outside looking around the car, something had been placed in his coffee! He recollected that it tasted rather bitter. But where was the car? Where were the Princess and her pretty niece?

It was a long time before his cramped limbs were sufficiently supple to enable him to walk, and then in the faint grey dawn he managed to crawl along a white unfamiliar high road that ran beside the rocky shore. For nearly two hours he walked in his wet clothes until he came to a tiny town which he discovered, was called Voltri, and was quite a short distance from Genoa.

The fascinating Winifred had evidently driven the car with his unconscious form covered up in the tonneau for some time before the pair had deposited him in the water, their intention being that the sea should itself dispose of his body.

For an hour he remained in the little inn drying his clothes and having his wound attended to, and then when able to travel, he took train back to San Remo, arriving late in the afternoon. He found to his astonishment he had remained unconscious at the edge of the tideless sea for about thirty hours.

His bandaged head was put down by the guests as due to an accident in the car, for he made no explanation. Presently, however, the hotel proprietor came to his room, and asked the whereabouts of the Princess and her niece, as they had not been seen since they left with him. In addition, the maid had suddenly disappeared, while the party owed a little bill of nearly one hundred pounds sterling.

“And Mr Tremlett?” Garrett asked. “He is still here, of course?”

“No, signore,” was the courtly Italian’s reply. “He left in a motor-car with Mr Clayton and his valet late the same night.”

Their destination was unknown. The little old hunchback had also left, Garrett was informed.

A week later, as Garrett entered the cosy sitting-room in Dover Street the Prince sprang from his chair, exclaiming:

“By Jove, Garrett! I’m glad to see you back. We began to fear that you’d met with foul play. What happened to you? Sit down, and tell me. Where’s the car?”

The chauffeur was compelled to admit his ignorance of its whereabouts, and then related his exciting and perilous adventure.

“Yes,” replied the handsome young adventurer, gaily. “It was a crooked bit of business, but we needn’t trouble further about the car, Garrett, for the fact is we’ve exchanged our ‘forty’ for that old hunchback’s mysterious ‘sixty.’ It’s at Meunier’s garage in Paris. But, of course,” he laughed, “you didn’t know who the hunchback really was. It was Finch Grey.”

“Finch Grey!” gasped Garrett, amazed, for he was the most renowned and expert thief in the whole of Europe.

“Yes,” he said, “we went to San Remo to meet him. It was like this. The Reverend Thomas was in Milan and got wind of a little coup at the Banca d’Italia which Finch Grey had arranged. The plot was one night to attack the strong-room of the bank, a tunnel to which had already been driven from a neighbouring house. The proceeds of this robbery – notes and gold – were to be brought down to San Remo by Finch Grey in his ‘sixty,’ the idea being to then meet the Princess and her niece, who were really only members of his gang. Our idea was to get friendly with the two ladies, so that when the car full of gold and notes arrived we should have an opportunity of getting hold of it. Our plans, however, were upset in two particulars, by the fact that a few days prior to my arrival the pair had quarrelled with the old hunchback, and secondly, because a friend of the Princess’s, staying at the hotel, had recognised you as a ‘crook.’ By some means the two women suspected that, on Finch Grey’s appearance, our intention was either to demand part of the proceeds of the bank robbery or expose them to the police. Therefore they put something in your coffee, the girl drove the car to the spot where you found yourself, and then they escaped to Genoa, and on to Rome. Finch Grey, who did not know who we were, was highly concerned with us regarding the non-return of the ladies. We suggested that we should go out in his ‘sixty’ with him to search for them, and he, fearing that you had met with an accident, consented. The rest was easy,” he laughed.

“How?”

“Well, we let him get half way to Oneglia, when we just slipped a handkerchief with a little perfume upon it, over his nose and mouth, and a few minutes later we laid him quietly down behind a wall. Then I turned the car back to where we had previously stored some pots of white paint and a couple of big brushes, and in an hour had transformed the colour of the car and changed its identification-plates. Imagine our joy when we found the back locker where the tools should have been crammed with bags of gold twenty lire pieces, while under the inside seat we found a number of neat packets of fifty and one-hundred and five-hundred lire notes. Just after midnight we slipped back through San Remo, and two days ago arrived safely in Paris with our valuable freight. Like to see some of it?” he added, and rising he pushed back the bookcase, opened the panel and took out several bundles of Italian notes. I saw also within a number of small canvas bags of gold.

“By this time, Garrett,” he added, laughing and pouring me out a drink, “old Finch Grey is gnashing his teeth, for he cannot invoke the aid of the police, and the women who intended to be avenged upon us for our daring are, no doubt, very sorry they ran away with our car, which, after all, was not nearly such a good one as the mysterious ‘sixty.’ Theirs wasn’t a particularly cheery journey, was it?” and lifting his glass he added, “So let’s wish them very good luck!”
