measure. The photographers were folding their camera. They stood it against the wall and began to search. Mannering toyed with the books at his side, letting the leaves flutter through his fingers. The routine was boring; the police took it as a matter of course. Men kept breathing on shiny surfaces to see if prints showed up, smothering places where they did with black graphite which they applied with a small camel-hair brush, then leaving it and searching for other prints. Gordon himself sat at the desk and opened drawer after drawer.
When he pulled the top right-hand drawer open Mannering said: âHe usually kept a gun in there.â
âIf I want information Iâll ask for it.â
âWhatâs got under your skin, Gordon?â
âYou always get under my skin. You amateurs who think youâre smart are a pain in the neck. And youâre the biggest pain. How long after you found the body did you send for us?â
âAbout twenty minutes.â
âThat was nineteen too long.â
âIf Iâd thought I could bring Bernstein round it would have been a couple of hours.â Mannering let the pages flutter, then shifted the book and picked up another. He knew Bernstein had secret hiding-places in some of those.
âKnow what the killer was after?â
âIf you want me to guess, I will.â
âAll right, guess.â
âJacob had the Diamond of Tears âknown as the Tear. Even you may have heard of it. I telephoned him about it tonight and promised to call him later. He didnât answer the second call and I came round to see if he was all right.â
âWhy shouldnât he have been?â
âBecause he didnât answer an expected telephone call.â
âHow did you get in?â
âThe murderer had opened the door for me.â
Gordon stopped taking oddments out of the desk and piling them up in front of him, leaned back in his chair, stuck a thumb in the armhole of his waist-coat, and said: âListen, Mannering, you were found on enclosed premises with the body of a murdered man. You had a chance to slip out and hide anything you lifted. We can hold you for that.â
âI can tell you twenty other ways you can make a fool of yourself,â said Mannering. The pages of the second book fluttered smoothly through his fingers as he watched the Yard man. âBut go ahead, hold me. That will teach me to send for the police when a friend of mine has been murdered.â
âFriend.â Gordon sneered the word.
âYes. And I choose my own.â
Gordon lit a cigarette and flicked the match across the room; it fell at Manneringâs feet.
âI asked you how you got in here.â
âAnd I told you. The murderer opened the door for me. If he wasnât the murderer Iâll eat my words.â
âYou saw him?â Gordon jumped up from the desk. âWhy didnât you say so?â
âBecause his face was masked and his hat pulled low over his eyes. And he kicked me before I knew what was coming. All I can tell you is that he was on the tall side, five ten or eleven, well-built, wearing dark clothes and a black Homburg. I gave the details to the constable two minutes after I spoke to him, and presumably theyâre going the rounds. Do you want me here any longer?â
Gordon growled: âYes.â He went out of the room, and Mannering picked up the third book and put it on his lap; the pages turned smoothly.
The police were working quietly, no one else took any notice of him. Downstairs, Gordonâs voice was raised, hectoring the constable.
Mannering picked up the fourth book. There were a hundred books in this room and he had no reason to think he would find a hiding-place in any of the first few which came to hand.
The pages stuck.
Gordon came back, scowling. Mannering slid his forefinger between the pages, and touched the soft texture of cotton wool.
âAre you keeping anything
