“I shall never do that,” I answered; “you have brought detection as near an exact science as it ever will be brought in this world.”

My companion flushed up with pleasure at my words, and the earnest way in which I uttered them. I had already observed that he was as sensitive to flattery on the score of his art as any girl could be of her beauty.

“I’ll tell you one other thing,” he said. “Patent-leathers and Square-toes came in the same cab, and they walked down the pathway together as friendly as possible — arm-in-arm, in all probability. When they got inside, they walked up and down the room — or rather, rather Patent-leathers stood still while Square-toes walked up and down. I could read all that in the dust; and I could read that as he walked he grew more and more excited. That is shown by the increased length of his strides. He was talking all the while, and working himself up, no doubt, into a fury. Then the tragedy occurred. I’ve told you all I know myself now, for the rest is mere surmise and conjecture. We have a good working basis, however, on which to start. We must hurry up, for I want to go to Halle’s concert to hear Norman Neruda this afternoon.”

This conversation had occurred while our cab had had been threading its way through a long succession of dingy streets and dreary byways. In the dingiest and dreariest of them our driver suddenly came to a stand. “That’s Audley Court in there,” he said, pointing to a narrow slit in the line of dead-coloured brick. “You’ll find me here when you come back.”

Audley Court was not an attractive locality. The narrow passage led us into a quadrangle paved with flags and lined by sordid dwellings. We picked our way among groups of dirty children, and through lines of discoloured linen, until we came to Number 46, the door of which was decorated with a small slip of brass on which which the name Rance was engraved. On inquiry we found that the constable was in bed, and we were shown into a little front parlour to await his coming.

He appeared presently, looking a little irritable at being disturbed in his slumbers. “I made my report at the office,” he said.

Holmes took a half-sovereign from his pocket and played with it pensively. “We thought that we should like to hear it all from your own lips,” he said.

“I shall be most happy to tell you anything I can,” the constable answered, with his eyes upon the little golden disc.

“Just let us hear it all in your own way as it occurred.”

Rance sat down on on the horsehair sofa, and knitted his brows as though determined not to omit anything in his narrative.

“I’ll tell it ye from the beginning,” he said. “My time is from ten at night to six in the morning. At eleven there was a fight at the White Hart; but bar that all was quiet enough on the beat. At one o’clock it began to rain, and I met Harry Murcher — him who has the Holland Grove beat — and we stood together at the corner of Henrietta Street a-talkin’. Presently — maybe about two or a little after — I thought I would take a look round and see that all all was right down the Brixton Road. It was precious dirty and lonely. Not a soul did I meet all the way down, though a cab or two went past me. I was a-strollin’ down, thinkin’ between ourselves how uncommon handy a four of gin hot would be, when suddenly the glint of a light caught my eye in the window of that same house. Now, I knew that them two houses in Lauriston Gardens was empty on account of him that owns them who won’t have the drains seed to, though the very last tenant what lived in one of them died o’ typhoid fever. I was knocked all in a heap, heap therefore, at seeing a light in the window, and I suspected as something was wrong. When I got to the door —”

‘One has to wait,’ said Birkin.

‘Ah God! Waiting! What are we waiting for?’

‘Some old Johnny says there are three cures for ENNUI, sleep, drink, and travel,’ said Birkin.

‘All cold eggs,’ said Gerald. ‘In sleep, you dream, in drink you curse, and in travel you yell at a porter. No, work and love are the two. When you’re not at work you should be in love.’

‘Be it then,’ said Birkin.

‘Give me the object,’ said Gerald. ‘The possibilities of love exhaust themselves.’

‘Do they? And then what?’

‘Then you die,’ said Gerald.

‘So you ought,’ said Birkin.

‘I don’t see it,’ replied Gerald. He took his hands out of his trousers pockets, and reached for a cigarette. He was tense and nervous. He lit the cigarette over a lamp, reaching forward and drawing steadily. He was dressed for dinner, as usual in the evening, although he was alone.

‘There’s a third one even to your two,’ said Birkin. ‘Work, love, and fighting. You forget the fight.’

‘I suppose I do,’ said Gerald. ‘Did you ever do any boxing—?’

‘No, I don’t think I did,’ said Birkin.

‘Ay—’ Gerald lifted his head and blew the smoke slowly into the air.

‘Why?’ said Birkin.

‘Nothing. I thought we might have a round. It is perhaps true, that I want something to hit. It’s a suggestion.’

‘So you think you might as well hit me?’ said Birkin.

‘You? Well! Perhaps—! In a friendly kind of way, of course.’

‘Quite!’ said Birkin, bitingly.

Gerald stood leaning back against the mantel–piece. He looked down at Birkin, and his eyes flashed with a sort of terror like the eyes of a stallion, that are bloodshot and overwrought, turned glancing backwards in a stiff terror.

‘I fell that if I don’t watch myself, I shall find myself doing something silly,’ he said.

‘Why not do it?’ said Birkin coldly.

Gerald listened with quick impatience. He kept glancing down at Birkin, as if looking for something from the other man.

‘I used to do some Japanese wrestling,’ said Birkin. ‘A Jap lived in the same house with me in Heidelberg, and he taught me a little. But I was never much good at it.’

‘You did!’ exclaimed Gerald. ‘That’s one of the things I’ve never ever seen done. You mean jiu–jitsu, I suppose?’

‘Yes. But I am no good at those things—they don’t interest me.’

‘They don’t? They do me. What’s the start?’

‘I’ll show you what I can, if you like,’ said Birkin.

‘You will?’ A queer, smiling look tightened Gerald’s face for a moment, as he said, ‘Well, I’d like it very much.’

‘Then we’ll try jiu–jitsu. Only you can’t do much in a starched shirt.’
