"If the murderer came in through the window while Sir Reginald was in the room, either the window was standing open or Sir Reginald opened it for him! Did Sir Reginald ever sit with his window open late at night at this time of year?" "Never once, sir," said Bisset confidently. "He likit fresh air outside fine but never kept his windies open much unless the weather was vera propitious." "Then," said Ned, "why should Sir Reginald have opened the window of his own accord to a stranger at the dead of night?" "Exactly!" said Mr. Rattar. "Thing seems absurd. He'd never do it." "That's my own opinion likewise, sir," put in Bisset. "It's only common sense," added the superintendent. "Then how came the window to be unfastened?" demanded Ned. "I've suggested a reason," said Simon. "As a blind? Sounds to me damned thin." Simon Rattar turned away from him with an air that suggested that he thought it time to indicate distinctly that he was in charge of the case and not the laird of Stanesland. "That's all we can do just now, Sutherland," he said. "No use disturbing the household any longer at present." Cromarty stepped up to him suddenly and asked: "Tell me honestly! Do you suspect anybody?" Simon shook his head decidedly. "No sufficient evidence yet. Good morning, Mr. Cromarty." Ned was following him to the door, his lips compressed and his eyes on the floor, when Bisset touched his arm and beckoned him back. "Excuse me, sir," said he, "but could you not manage just to stop on for a wee bit yet?" Ned hesitated. "They won't be wanting visitors, Bisset." "They needn't know if you don't want them to, sir. Lady Cromarty is shut up in her room, and the others are keeping out of the way. If you wouldn't mind my giving you a little cold luncheon in my sitting room, sir, I'd like to have your help. I'm making a few sma' bits of investigation on my own. You're one of the family, sir, and I know you'll be wanting to find out who killed the master." Ned's eye flashed suddenly. "By God, I'll never rest in this world or the next till I do! All right, I'll wait for a bit." XII CICELY Ned Cromarty waited in the hall while Bisset went to the door with the Procurator Fiscal and Superintendent of Police. As he stood there in the darkened silence of the house, there came to his ears for an instant the faint sound of a voice, and it seemed to be a woman's. With that the current of his thoughts seemed to change, and when Bisset returned he asked, though with marked hesitation: "Do you think, Bisset, I could do anything for any of them, Mr. Malcolm Cromarty, or--er--Miss Farmond?" Bisset considered the point judicially. It was clear he felt that the management of the household was in his hands now. "I am sure Miss Farmond would be pleased, sir--poor young lady!" "Do you really think so?" said Ned, and his manner brightened visibly. "Well, if she won't mind----" "I think if you come this way, sir, you will find her with Sir Malcolm."
