recognized the note of sarcasm.
‘You know my methods, Watson,’ said the doctor.
‘Dead man wearing an overcoat; you conclude he came in the door to find the killer waiting. You guess the two men faced each other squarely with the killer in the chair by the fireplace, and from the path of the wound you guess the gun was in the killer’s left hand.’
‘Damned good cigarettes these Germans give you,’ said the doctor, holding it in the air and looking at the smoke.
‘And an ex-soldier because he pierced the heart with the first shot.’ The doctor inhaled and nodded. ‘Have you noticed that all three of us are still wearing overcoats?’ said Douglas. ‘It’s bloody cold in here and the gas meter is empty and the supply disconnected. And not many soldiers are expert shots, doc, and not one in a million is an expert with a pistol, and by your evidence a German pistol at that. And you think the killer had a key because you can’t see any signs of the door being forced. But my Sergeant could get through that door using a strip of celluloid faster than you could open it with a key, and more quietly too.’
‘Oh,’ said the doctor.
‘Now, what about a time of death?’ said Douglas.
All doctors hate to estimate the time of death and this doctor made sure the policemen knew that. He shrugged. ‘I can think of a number and double it.’
‘Think of a number, doc,’ said Douglas, ‘but don’t double it.’
The doctor, still lolling on the couch, pinched out his cigarette and put the stub away in a dented tobacco tin. ‘I took the temperature when I arrived. The normal calculation is that a body cools one-and-a-half degrees Fahrenheit per hour.’
‘I’d heard a rumour to that effect,’ said Douglas.
The doctor gave him a mirthless grin as he put the tin in his overcoat pocket, and watched his feet as he made the toes touch together again. ‘Could have been between six and seven this morning.’
Douglas looked at the uniformed Sergeant. ‘Who reported it?’
‘The downstairs neighbour brings a bottle of milk up here each morning. He found the door open. No smell of cordite or anything,’ added the Sergeant.
The doctor chortled. When it turned into a cough he thumped his chest. ‘No smell of cordite,’ he repeated. ‘I’ll remember that one, that’s rather rich.’
‘You don’t know much about coppers, doc,’ said Douglas. ‘Specially when you take into account that you are a Police Surgeon. The uniformed Sergeant here, an officer I’ve never met before, is politely hinting to me that he thinks the time of death was earlier. Much earlier, doc.’ Douglas went over to the elaborately painted corner cupboard and opened it to reveal an impressive display of drink. He picked up a bottle of whisky and noted without surprise that most of the labels said ‘Specially bottled for the Wehrmacht’. Douglas replaced the bottles and closed the cupboard. ‘Have you ever heard of postmortem lividity, doctor?’ he said.
‘Death might have been earlier,’ admitted the doctor. He was sitting upright now and his voice was soft. He, too, had noticed the coloration that comes from settling of the blood.
‘But not before midnight.’
‘No, not before midnight,’ agreed the doctor.
‘In other words death took place during curfew?’
‘Very likely.’
‘Very likely?’ said Douglas caustically.
‘Definitely
during curfew,’ admitted the doctor.
‘What kind of a game are you playing, doc?’ said Douglas. He didn’t look at the doctor. He went to thefireplace and examined the huge pile of charred paper that was stuffed into the tiny grate. The highly polished brass poker was browned with smoke marks. Someone had used it to make sure that every last piece of paper was consumed by the flames. Again Douglas put his hand into the feathery layers of ash; there must have been a huge pile of foolscap and it was quite cold. ‘Contents of his pockets, Harry?’
‘Identity card, eight pounds,
