Tanner was as nearly excited as his dignity would allow. There could be little doubt, he felt, that this Douglas was indeed the man of whom he was in search. The man’s size—a small man would take short steps—the little, hobnailed boots, the wet and muddy trousers, the goatee beard—these points considered cumulatively, made the evidence of identity almost overwhelming. And in addition he had been out all the night of the tragedy, and had returned in the morning shaken and clamouring for brandy. Enough evidence to hang a man, Tanner thought with satisfaction. He turned again to the porter.

‘What day did he come here first?’

‘I looked that up when I went to the office. It was on the Friday evening before.’

‘He left no address, I suppose?’

‘Not ’im,’ said the porter with a wink.

‘How did he go away? Did he get a cab?’

‘Keb?’ returned the other disgustedly. ‘Not ’im. ’E took ’is bag in ’is hand and just ’ooked it on ’is blooming feet.’

Tanner replied absently. He was thinking that a man who departed on foot from an hotel without leaving an address might not be so easy to trace. And the best description of his appearance he could get was too vague to be of much use. The porter had not noticed the colour of the man’s eyes, if there was any scar or mark on his face or hands, the shape of his ears, any peculiarity in his gait—none of the matters on which identification depends. Tanner could only remind himself that a general hazy notion was better than no notion at all.

He went to the office and saw the proprietor. The latter was a tall weedy individual, dilapidated looking as his own hotel. But he spoke civilly, and exerted himself to answer the Inspector’s questions, calling in various maids, and an untidy waiter for the latter’s interrogations. Unfortunately, none of them could tell anything Tanner had not already learned.

The man had registered ‘William Douglas, Fulham Street, Birmingham,’ and with the proprietor’s permission Tanner cut out and pocketed the leaf. Then he asked to see the room the visitor had occupied.
