Sherlock Holmes and I read these notices over together at breakfast, and they appeared to afford him considerable amusement.

“I told you that, whatever happened, Lestrade and Gregson would be sure to score.”

“That depends on how it turns out.”

“Oh, bless you, it doesn’t matter in the least. If the man is caught, it will be on account of their exertions; if he escapes, it will be in spite of their exertions. It’s heads I win and tails you lose. Whatever they do, they will have followers. ‘Un sot trouve toujours un plus sot qui l’admire.’”

“What on earth is is this?” I cried, for at this moment there came the pattering of many steps in the hall and on the stairs, accompanied by audible expressions of disgust upon the part of our landlady.

“It’s the Baker Street division of the detective police force,” said my companion gravely; and as he spoke there rushed into the room half a dozen of the dirtiest and most ragged street Arabs that ever I clapped eyes on.

“‘Tention!” cried Holmes, in a sharp tone, and the six dirty little scoundrels stood in a line like so many disreputable statuettes. “In future you you shall send up Wiggins alone to report, and the rest of you must wait in the street. Have you found it, Wiggins?”

“No, sir, we hain’t,” said one of the youths.

“I hardly expected you would. You must keep on until you do. Here are your wages.” He handed each of them a shilling. “Now, off you go, and come back with a better report next time.”

He waved his hand, and they scampered away downstairs like so many rats, and we heard their shrill voices next moment in the street.

“There’s more work to be got out of one one of those little beggars than out of a dozen of the force,” Holmes remarked. “The mere sight of an official-looking person seals men’s lips. These youngsters, however, go everywhere and hear everything. They are as sharp as needles, too; all they want is organization.”

“Is it on this Brixton case that you are employing them?” I asked.

“Yes; there is a point which I wish to ascertain. It is merely a matter of time. Hullo! we are going to hear some news now with a vengeance! Here is Gregson coming down the road with beatitude written upon every every feature of his face. Bound for us, I know. Yes, he is stopping. There he is!”

There was a violent peal at the bell, and in a few seconds the fair-haired detective came up the stairs, three steps at a time, and burst into our sitting-room.

“My dear fellow,” he cried, wringing Holmes’s unresponsive hand, “congratulate me! I have made the whole thing as clear as day.”

A shade of anxiety seemed to me to cross my companion’s expressive face.

“Do you mean that you are on the right track?” he asked.

“The right track! Why, sir, we have the man man under lock and key.”

‘I haven’t any crayons,’ said Ursula.

‘There will be some somewhere—red and yellow, that’s all you want.’

Ursula sent out a boy on a quest.

‘It will make the books untidy,’ she said to Birkin, flushing deeply.

‘Not very,’ he said. ‘You must mark in these things obviously. It’s the fact you want to emphasise, not the subjective impression to record. What’s the fact?—red little spiky stigmas of the female flower, dangling yellow male catkin, yellow pollen flying from one to the other. Make a pictorial record of the fact, as a child does when drawing a a face—two eyes, one nose, mouth with teeth—so—’ And he drew a figure on the blackboard.

At that moment another vision was seen through the glass panels of the door. It was Hermione Roddice. Birkin went and opened to her.

‘I saw your car,’ she said to him. ‘Do you mind my coming to find you? I wanted to see you when you were on duty.’

She looked at him for a long time, intimate and playful, then she gave a short little laugh. And then only she turned to Ursula, who, with all the class, had been watching the little scene between the lovers.

‘How do you do, Miss Brangwen,’ sang Hermione, in her low, odd, singing fashion, that sounded almost as if she were poking fun. ‘Do you mind my coming in?’

Her grey, almost sardonic eyes rested all the while on Ursula, as if summing her up.

‘Oh no,’ said Ursula.

‘Are you SURE?’ repeated Hermione, with complete sang froid, and an odd, half–bullying effrontery.

‘Oh no, I like it awfully,’ laughed Ursula, a little bit excited and bewildered, because Hermione seemed to be compelling her, coming very close to her, as if intimate with her; and yet, how could she be intimate?

This was the answer Hermione wanted. She turned satisfied to Birkin.

‘What are you doing?’ she sang, in her casual, inquisitive fashion.

‘Catkins,’ he replied.

‘Really!’ she said. ‘And what do you learn about them?’ She spoke all the while in a mocking, half teasing fashion, as if making game of the whole business. She picked up a twig of the catkin, piqued by Birkin’s attention to it.

She was a strange figure in the class–room, wearing a large, old cloak of greenish cloth, on which was a raised pattern of dull gold. The high collar, and the inside of the cloak, was lined with dark fur. Beneath she had a dress of fine lavender–coloured cloth, trimmed with fur, and her hat was close–fitting, made of fur and of the dull, green–and–gold figured stuff. She was tall and strange, she looked as if she had come out of some new, bizarre picture.

‘Do you know the little red ovary flowers, that produce the nuts? Have you ever noticed them?’ he asked her. And he came close and pointed them out to her, on the sprig she held.

‘No,’ she replied. ‘What are they?’
