A conversation between two old military gossips in my Club put me on the track of General Macarthur. A man who had recently returned from the Amazon gave me a devastating resume of the activities of one Philip Lombard. An indignant memsahib[64] in Majorca recounted the tale of the Puritan Emily Brent and her wretched servant girl. Anthony Marston I selected from a large group of people who had committed similar offences. His complete callousness and his inability to feel any responsibility for the lives he had taken made him, I considered, a type dangerous to the community and unfit to live. Ex-Inspector Blore came my way quite naturally, some of my professional brethren discussing the Landor case with freedom and vigour. I took a serious view of his offence. The police, as servants of the law, must be of a high order of integrity. For their word is perforce believed by virtue of their profession.
