“Why a fire?” he asked once. “Had they always a fire in this small room on a spring evening?”

Mortimer Tregennis explained that the night was cold and damp. For that reason, after his arrival, the fire was lit. “What are you going to do now, Mr. Holmes?” he asked.

My friend smiled and laid his hand upon my arm. “I think, Watson, that I shall resume that course of tobacco-poisoning which you have so often and so justly condemned,” said he. “With your permission, gentlemen, we will now return to our cottage, for I am not aware that any new factor is likely to come to our notice here. I will turn the facts over in my mind, Mr. Tregennis, and should anything occur to me I will certainly communicate with you and the vicar. In the meantime I wish you both good-morning.”

It was not until long after we were back in Poldhu Cottage that Holmes broke his complete and absorbed silence. He sat coiled in his armchair, his haggard and ascetic face hardly visible amid the blue swirl of his tobacco smoke, his black brows drawn down, his forehead contracted, his eyes vacant and far away. Finally he laid down his pipe and sprang to his feet.

“It won’t do, Watson!” said he he with a laugh. “Let us walk along the cliffs together and search for flint arrows. We are more likely to find them than clues to this problem. To let the brain work without sufficient material is like racing an engine. It racks itself to pieces. The sea air, sunshine, and patience, Watson — all else will come.

“Now, let us calmly define our position, Watson,” he continued as we skirted the cliffs together. “Let us get a firm grip of the very little which we do know, so that when fresh facts arise we may be ready to fit them into their places. I take it, in the first place, that neither of us is prepared to admit diabolical intrusions into the affairs of men. Let us begin by ruling that entirely out of our minds. Very good. There remain three persons who have been grievously stricken by some conscious or unconscious human agency. That is firm ground. Now, when did this occur? Evidently, assuming his narrative to be true, it was immediately after Mr. Mortimer Tregennis had left the room. That is a very important point. The presumption is that it was within a few minutes afterwards. The cards still lay upon the table. It was already past their usual hour for bed. Yet they had not changed their position or pushed back their chairs. I repeat then, that the occurrence was immediately after his departure, and not later than eleven o’clock last night.

“Our next obvious step is to check, so far as we can, the movements of Mortimer Tregennis after he left the room. In this there is no difficulty, and they seem to be above suspicion. Knowing my methods as you do, you were, of course, conscious of the somewhat clumsy water-pot expedient by which I obtained a clearer impress of his foot than might otherwise have been possible. The wet, sandy path took it admirably. Last night was also wet, you will remember, and it was not difficult — having obtained a sample print — to pick out his track among others and to follow his movements. He appears to have walked away swiftly in the direction of the vicarage.

‘Is that you?’ Connie asked him.

He twisted and looked at the enlargement above his head.

‘Ay! Taken just afore we was married, when I was twenty–one.’ He looked at it impassively.

‘Do you like it?’ Connie asked him.

‘Like it? No! I never liked the thing. But she fixed it all up to have it done, like.’

He returned to pulling off his boots.

‘If you don’t like it, why do you keep it hanging there? Perhaps your wife would like to have it,’ she said.

He looked up at her with a sudden grin.

‘She carted off iverything as was worth taking from th’ ‘ouse,’ he said. ‘But she left THAT!’

‘Then why do you keep it? for sentimental reasons?’

‘Nay, I niver look at it. I hardly knowed it wor theer. It’s bin theer sin’ we come to this place.’

‘Why don’t you burn it?’ she said.

He twisted round again and looked at the enlarged photograph. It was framed in a brown–and–gilt frame, hideous. It showed a clean–shaven, alert, very young–looking man in a rather high collar, and a somewhat plump, bold young woman with hair fluffed out and crimped, and wearing a dark satin blouse.

‘It wouldn’t be a bad idea, would it?’ he said.

He had pulled off his boots, and put on a pair of slippers. He stood up on the chair, and lifted down the photograph. It left a big pale place on the greenish wall–paper.

‘No use dusting it now,’ he said, setting the thing against the wall.

He went to the scullery, and returned with hammer and pincers. Sitting where he had sat before, he started to tear off the back–paper from the big frame, and to pull out the sprigs that held the backboard in position, working with the immediate quiet absorption that was characteristic of him.

He soon had the nails out: then he pulled out the backboards, then the enlargement itself, in its solid white mount. He looked at the photograph with amusement.

‘Shows me for what I was, a young curate, and her for what she was, a bully,’ he said. ‘The prig and the bully!’

‘Let me look!’ said Connie.

He did look indeed very clean–shaven and very clean altogether, one of the clean young men of twenty years ago. But even in the photograph his eyes were alert and dauntless. And the woman was not altogether a bully, though her jowl was heavy. There was a touch of appeal in her.

‘One never should keep these things,’ said Connie. ‘That one shouldn’t! One should never have them made!’

He broke the cardboard photograph and mount over his knee, and when it was small enough, put it on the fire.

‘It’ll spoil the fire though,’ he said.

The glass and the backboard he carefully took upstairs.

The frame he knocked asunder with a few blows of the hammer, making the stucco fly. Then he took the pieces into the scullery.

‘We’ll burn that tomorrow,’ he said. ‘There’s too much plaster–moulding on it.’
