speaking on criminal psychology. I was looking forward to hearing about it.â
âI didnât go.â
âThatâs a shame.â
âI know. Heâs done some brilliant work. Heâs bringing together social influences, observed behaviours and phrenological analysis to create a typology of crime. If heâs right, weâll be able to diagnose the criminal character in early youth and treat â even remedy it â accordingly.â
âPhrenology?â Antonia giggled behind her hand.
âI know, practically everyone thought it was bunkum when I was at medical school.â
âMaybe they changed their minds later? I mean, after youâd had to leave.â
âItâs more recent than that. Thereâs been a lot of work to systematise it and relate it to what happens to patients when particular parts of their brains are destroyed by injury or disease. Bainâs even persuaded John Stuart Mill that the science is sound.â
âA persuasive gentleman then. Something important must have happened to tear you away from hearing him.â
âThatâs what I wanted to ask you about, Antonia. I was just getting ready to go when I was called to the Chief Constableâs house and told to look for a disappearing Duke. His wife is worried that heâs been away from home for a few days, and the Chief thinks itâs a matter of importance to the State that we find him.â
âNot quite your usual calibre of business, Archie. One man temporarily missing, no-one injured.â
âI know. Frankly, I resent being used as a private detective for the aristocracy. But the fact is heâs still missing. Iâve tried to track him down in the disreputable haunts heâs known to have frequented, but no-oneâs seen him. I donât think he wants to be found.â
âAnd so you thought youâd ask me? In case heâd visited this âdisreputable hauntâ?â Antonia pulled her gown more tightly around her.
âI have to ask you, Antonia. Itâs important.â
Antonia looked straight at him, her lips thin and her delicate hands clenched in her lap.
âIt hurts me, Archibald. It hurts me because it exposes the inequality in our friendship. Youâre a policeman, Iâm a whore. You could have me closed down or arrested if you chose. I want to be your friend, Archie, not your informer.â
âIâm sorry I asked.â
âBut youâll be in bad trouble if you donât find this Duke?â
âYes.â
âAll right then. Iâll help if I can. Who is it?â
âWilliam Bothwell-Scott. The Duke of Dornoch.â
Antonia breathed in sharply. She was holding her hands together, thought Allerdyce, as if she was trying to stop them from shaking. She stood up and went over to the window, the light bleaching the goldenness of her complexion. Allerdyce stood and went over to her.
âAre you all right, Antonia?â
She turned and smiled thinly at him.
âYes, Archie, quite all right.â
âI thought you shuddered.â
âSometimes I wish you were a less acute student of human nature, Archibald. I confess that that name caused me a moment of pain.â
âMay I ask why?â
âIt is a pain which I buried long ago and which I have no wish to resurrect. But in answer to your immediate question, I have no knowledge of the gentlemanâs recent whereabouts.â
âIâm sorry to have upset you.â
She touched him gently on the arm.
âYou were only doing your duty, Archie. But please, leave me to compose myself before my next visitor arrives. And Archie, next time you come please come as my friend and not as a policeman.â
Chapter 8
Allerdyce and McGillivray shared a second-class compartment on the Edinburgh to Queensferry train. The Inspector opened the window a few inches to let his pipe smoke out and to breathe in the fresh air, but as
