"Charles," said Winter earnestly, placing a hand on his colleague's shoulder, "we gain nothing by rushing our fences. This is the toughest job we've handled this year; there's a hard road to travel before we sit down and prepare a brief for counsel."

"Of course, I meant the story up to the six o'clock instalment."

Winter smiled. He sprang into the car, the chauffeur having already started the engine in obedience to a word from the Superintendent.

"Stop at the Brondesbury police station," was the order, and Furneaux was left alone. He reëntered the house and crooked a finger at the butler, who had not summoned up courage to retire to his own sanctum, though a midday meal was awaiting him.

"Take me upstairs," said the detective. "I shall not detain you many minutes. Then you and I will have a snack together and you'll borrow a bicycle for me, and I sha'n't trouble you any more till a late hour."

"No trouble at all, sir," Tomlinson assured him. "If I could advance your inquiry in the least degree I'd fast cheerfully all day."

"What I like about you, Tomlinson, is your restraint," said Furneaux. "Many a man would have offered to fast a week, not meaning to deny himself a toothful five minutes longer than was avoidable. Now you really mean what you say——Ah, this is Mr. Robert's den. And that is his bedroom, with dressing-room adjoining. Very cozy, to be sure. Of course, the rooms have been dusted regularly since he disappeared on Saturday?"

"Every day, sir."

"Well, I hate prying into people's rooms. Beastly liberty, I call it. Now for Mr. Hilton's."
