"Sorry for your planking," Grant apologized as the blood collected in a little pool. "Don't worry," Drysdale said. "It will scrub. This the man you wanted?"

"Yes."

He considered the dark, unconscious face for a while.

"What do you want him for, if it isn't an indiscreet question?"

"Murder."

"Really?" said Drysdale, very much as though Grant had said "sheep-stealing." He considered the man again. "Is he a foreigner?"

"No; a Londoner."

"Well, at the moment he looks very much as if he would cheat the gallows after all, doesn't he?"

Grant looked sharply at the man he was tending. Was he as bad as that? Surely not!

As Carninnish House swam up to them from across the water Grant said, "He was staying with the Logans at the manse. I can't very well take him back there. The hotel is the best place, I think. Then the Government can bear all the bother of the business."

But as they floated swiftly in to the landing-stage, and Pidgeon, who had been on the lookout for their return, came down to meet them, Drysdale said, "The man we went for is a bit knocked out. Which room was the fire lit in for Mr. Grant?"

"The one next yours, sir."

"Well, we'll carry this man there. Then tell Matheson to go over to Garnie for Dr. Anderson, and tell the Garnie Hotel people that Mr. Grant is staying the night with me, and bring over his things."

Grant protested at this unnecessary generosity. "Why, the man stuck his friend in the back!" he said.

"It isn't for him I'm doing it," Drysdale smiled, "though I wouldn't condemn my worst enemy to the hotel here. But you don't want to lose your man now that you've got him. Judging entirely by appearances, you had a very fine time getting him. And by the time they had lit a smoking fire in one of the glacial bedrooms over there" — he indicated the hotel on the point across the river — "and got him to bed, your man would be as good as dead. Whereas here there is the room you would have had to wash in, all warm and ready. It is far easier and better to dump the man there. And, Pidgeon!" as the man was turning away, "keep your mouth entirely closed. This gentleman met with an accident while boating. We observed it, and went out to his assistance."

"Very good, sir," said Pidgeon.

So Grant and Drysdale, between them, carried the limp heap upstairs, and rendered first aid in the big firelit bedroom; and then, between them, Pidgeon and Grant got him to bed, while Drysdale wrote a note to Mrs. Dinmont explaining that her guest had met with a slight accident and would stay here for the night. He was suffering from slight concussion, but would they not be alarmed.

Grant had just changed into some things of his host's, and was waiting at the bedside until dinner should be announced, when there was a knock at the door, and in answer to his "Come in," Miss Dinmont walked into the room. She was bareheaded and carried a small bundle under her arm, but appeared to be completely self-possessed.

"I've brought down some things of his," she said, and went over to the bed and dispassionately examined Lamont. For the sake of saying something, Grant said that they had sent for the doctor, but it was in his — Grant's — opinion a simple concussion. He had a cut on the back of the head.

"How did it happen?" she asked. But Grant had been facing this difficulty all the time he was changing out of his own wet things.

"We met Mr. Drysdale, and he offered to take us out. Mr. Lowe's foot slipped on the edge of the jetty, and the back of his head came in contact with it as he fell."

She nodded. She seemed to be puzzling over something and not to be able to make herself articulate. "Well, I'm going to stay and look after him tonight. It's awfully good of Mr. Drysdale to take him in." She untied her bundle matter-of-factly. "Do you know, I had a presentiment this morning when we were going up the river that something was going to happen. I'm so glad it's this and nothing worse. It might have been somebody's death, and that would have been incurable." There was a little pause, and, still busy, she said over her shoulder, "Are you staying the night with Mr. Drysdale too?"

Grant said "Yes," and on the word the door opened and Drysdale himself came in.

"Ready, Inspector? You must be hungry," he said, and then he saw Miss Dinmont. From that moment Grant always considered Drysdale a first-class «intelligence» man wasted. He didn't "bat an eyelid."

"Well, Miss Dinmont, were you anxious about your truant? There isn't any need, I think. It's just a slight concussion. Dr. Andersen will be along presently."

With another woman it might have passed muster, but Grant's heart sank as he met the Dinmont girl's intelligent eye. "Thank you for having him here," she said to Drysdale. "There isn't much to do till he comes round. But I'll stay the night, if you don't mind, and look after him." And then she turned to Grant and said deliberately, "Inspector of what?"

"Schools," said Grant on the spur of the moment, and then wished he hadn't. Drysdale, too, knew that it was a mistake, but loyally backed him up.

"He doesn't look it, does he? But then inspecting is the last resort of the unintellectual. Is there anything I can get you before we go and eat, Miss Dinmont?"

"No, thank you. May I ring for the maid if I want anything?"

"I hope you will. And for us if you want us. We're only in the room below." He went out and moved along the corridor, but, as Grant was following, she left the room with him and drew the door to behind her.

"Inspector," she said, "do you think I'm a fool? Don't you realize that for seven years I have worked in London hospitals? You can't treat me as a country innocent with any hope of success. Will you be good enough to tell me what the mystery is?"

Drysdale had disappeared downstairs. He was alone with her, and he felt that to tell her another untruth would be the supreme insult. "All right, Miss Dinmont, I'll tell you the truth. I didn't want you to know the truth before because I thought it might save you from — from feeling sorry about things. But now it can't be helped. I came from London to arrest the man you had staying with you. He knew what I had come for when I came in at teatime, because he knows me by sight. But when he came with me as far as the torof the road he bolted. In the end he took to a boat, and it was in diving from the boat when we followed that he cut his head open."

"And what do you want him for?"

It was inevitable. "He killed a man in London."

"Murder!" The word was a statement, not a question. She seemed to understand that, if it had been otherwise, the inspector would have said manslaughter. "Then his name is not Lowe?"

"No; his name is Lamont — Gerald Lamont."

He was waiting for the inevitable feminine outburst of "I don't believe it! He wouldn't do such a thing!" but it did not come.

"Are you arresting him on suspicion, or did he do the thing?"

"I'm afraid there isn't any doubt about it," Grant said gently.

"But my aunt — is she — how did she come to send him here?"

"I expect Mrs. Everett was sorry for him. She'd known him some time."

"I only met my aunt once in the time I've been in London — we didn't like each other — but she didn't strike me as a person to be sorry for a wrongdoer. I'd be much more likely to believe she did the thing herself. Then he isn't even a journalist?"

"No," Grant said; "he's a bookmaker's clerk."

"Well, thank you for telling me the truth at last," she said. "I must get things ready for Dr. Anderson now."

"Are you still going to look after him?" Grant asked involuntarily. Was the outburst of disbelief coming now?

"Certainly," said this remarkable girl. "The fact that he is a murderer doesn't alter the fact that he has concussion, does it? — nor the fact that he abused our hospitality alter the fact that I'm a professional nurse? And even if it weren't for that, perhaps you know that in the old days in the Highlands a guest received hospitality and sanctuary even if he had his host's brother's blood on his sword. It isn't often I boost the High-lands," she added, "but this is rather a special occasion." She gave a little catch of her breath that might have been a laugh or a sob, and was probably half one, half the other, and went back into the room to look after the man who had so unscrupulously used herself and her home.
