"Very happy, I'm sure, to do the best I can," Sir Allan murmured, lighting a fresh cigarette. "I wish you'd sit down to it, though. I suppose it's about that murder we were mixed up in? Horrid affair it was."

"Yes, it was a very horrid affair," Mr. Brown repeated slowly.

"They haven't caught the man yet, I suppose?"

"They have not—yet."

Sir Allan shrugged his fine shoulders.

"I fancy their chance is a poor one now, then," he remarked, emitting a little cloud of smoke from his lips, and watching it curl upward in a faint blue wreath to the ceiling. "How differently they manage affairs on the Continent! Such a crime would not go undetected a day there."

"It will not be undetected here many more days," Mr. Brown said. "My own belief is that a warrant is already issued for the apprehension of the supposed murderer, and I should not be surprised to hear that at this very moment the police were watching this house."

Sir Allan looked hard at his guest, and elevated his eyebrows.

"This is a very serious matter, Mr. Brown," he said, looking at him steadily in the face. "Do I understand——?"

"I will explain," Mr. Brown interrupted quietly. "On my return to Falcon's Nest yesterday, I find that during my absence the cottage has been entered, apparently by some one in authority, for keys have been used. My cabinet has been forced open, and a number of my private letters and papers have been taken away. Certain other investigations have also been made, obviously with the same object."
