The two girls drifted swiftly along. In front of them, at the corner of the lake, near the road, was a mossy boat–house under a walnut tree, and a little landing–stage where a boat was moored, wavering like a shadow on the still grey water, below the green, decayed poles. All was shadowy with coming summer.

Suddenly, from the boat–house, a white figure ran out, frightening in its swift sharp transit, across the old landing–stage. It launched in a white arc through the air, there was a bursting of the water, and among the smooth ripples a swimmer was making out to space, in a centre of faintly heaving motion. The whole otherworld, wet and remote, he had to himself. He could move into the pure translucency of the grey, uncreated water.

Gudrun stood by the stone wall, watching.

‘How I envy him,’ she said, in low, desirous tones.

‘Ugh!’ shivered Ursula. ‘So cold!’

‘Yes, but how good, how really fine, to swim out there!’ The sisters stood watching the swimmer move further into the grey, moist, full space of the water, pulsing with his own small, invading motion, and arched over with mist and dim woods.

‘Don’t you wish it were you?’ asked Gudrun, looking at Ursula.

‘I do,’ said Ursula. ‘But I’m not sure—it’s so wet.’

‘No,’ said Gudrun, reluctantly. She stood watching the motion on the bosom of the water, as if fascinated. He, having having swum a certain distance, turned round and was swimming on his back, looking along the water at the two girls by the wall. In the faint wash of motion, they could see his ruddy face, and could feel him watching them.

‘It is Gerald Crich,’ said Ursula.

‘I know,’ replied Gudrun.

And she stood motionless gazing over the water at the face which washed up and down on the flood, as he swam steadily. From his separate element he saw them and he exulted to himself because of his own advantage, his possession of a world to himself. He was immune and perfect. He loved his own vigorous, thrusting motion, and the violent impulse of the very cold water against his limbs, buoying him up. He could see the girls watching him a way off, outside, and that pleased him. He lifted his arm from the water, in a sign to them.

‘He is waving,’ said Ursula.

‘Yes,’ replied Gudrun. They watched him. He waved again, with a strange movement of recognition across the difference.

‘Like a Nibelung,’ laughed Ursula. Gudrun said nothing, only stood still looking over the water.

Gerald suddenly turned, and was swimming away swiftly, with a side stroke. He was alone now, alone and immune in the middle of the waters, which he had all to himself. He exulted in his isolation in the new element, unquestioned and unconditioned. He was happy, thrusting with his legs and all his body, without bond or connection anywhere, just himself in the watery world.

Gudrun envied him almost painfully. Even this momentary possession of pure isolation and fluidity seemed to her so terribly desirable that she felt herself as if damned, out there on the high–road.

As he spoke there was a sharp ring at the bell. Sherlock Holmes rose softly and moved his chair in the direction of the door. We heard the servant pass along the hall, and the sharp click of the latch as she opened it.

“Does Dr. Watson live here?” asked a clear but rather harsh voice. We could not hear the servant’s reply, but the door closed, and someone began to ascend the stairs. The footfall was an uncertain and shuffling one. A look of surprise passed over the face of my companion as he listened to it. It came slowly along the passage, and there was a feeble tap at the door.

“Come in,” I cried.

At my summons, instead of the man of violence whom we expected, a very old and wrinkled woman hobbled into the apartment. She appeared to be dazzled by the sudden blaze of light, and after dropping a curtsey, she stood blinking at us with her bleared eyes and fumbling in her pocket with nervous, shaky fingers. I glanced at my companion, and his face had assumed such a disconsolate expression that it was all I could do to keep my countenance.

The old crone drew out an evening paper, and pointed at our advertisement. “It’s this as has brought me, good gentlemen,” she said, dropping another curtsey; “a gold wedding ring in the Brixton Road. It belongs to my girl Sally, as was married only this time twelvemonth, which her husband is steward aboard a Union boat, and what he’d say if he comes ‘ome and found her without her ring is more than I can think, he being short enough at the best o’ times, but more especially when he has the drink. If it please you, she went to the circus last night along with —”

“Is that her ring?” I asked.

“The Lord be thanked!” cried the old woman; “Sally will be a glad woman this night. That’s the ring.”

“And what may your address be?” I inquired, taking up a pencil.

“13, Duncan Street, Houndsditch. A weary way from here.”

“The Brixton Road does not lie between any circus and Houndsditch,” said Sherlock Holmes sharply.

The old woman faced round and looked keenly at him from her little red-rimmed eyes. “The gentleman asked me for my address,” she said. “Sally lives in lodgings at 3, Mayfield Place, Peckham.”

“And your name is?”

“My name is Sawyer — hers is Dennis, which Tom Dennis married her — and a smart, clean lad, too, as long as he’s at sea, and no steward in the company more thought of; but when on shore, what with the women and what with liquor shops —”

“Here is your ring, Mrs. Sawyer,” I interrupted, in obedience to a sign from my companion; “it clearly belongs to your daughter, and I am glad to be able to restore it to the rightful owner.”

With many mumbled blessings and protestations of gratitude the old crone packed it away in her pocket, and shuffled off down the stairs. Sherlock Holmes sprang to his feet the moment that she was gone and rushed into his room. He returned in a few seconds enveloped in an ulster and a cravat. “I’ll follow her,” he said, hurriedly; “she must be an accomplice, and will lead me to him. Wait up for me.” The hall door had hardly slammed behind our visitor before Holmes had descended the stair. Looking through the window I could see her walking feebly along the other side, while her pursuer dogged her some little distance behind. “Either his whole theory is incorrect,” I thought to myself, “or else he will be led now to the heart of the mystery.” There was no need for him to ask me to wait up for him, for I felt that sleep was impossible until I heard the result of his adventure.
