A clatter of footsteps on the other side of the partition door answered this; then the bolt flashed back, the door whirled open, two figures—one on the very heels of the other—came tumbling into sight, and then there was mischief!
Cleek sprang, and a click of steel sounded. The doctor, caught in a sort of throttle-hold, went down with him upon the floor; the colonel, unable to check himself in time, sprawled headlong over them, and by the time he could pull himself to his knees young Bridewell was upon him, and there were gyves upon his wrists as well as upon the doctor's.
"Got you, you pretty pair!" said Cleek, as he rose to his feet and shut a tight hand upon the collar of the manacled doctor; "got you, you dogs, and your little game is up. Oh, you needn't bluster, doctor; you needn't come the outraged innocence, Colonel. You'll, neither of you, bolster up the rascally claim of your worthy confederate, the Tackbun Claimant; and your game with the X-rays, your devil's trick of rotting away a man's arm to destroy tattooed evidence of a rank imposter's guilt is just so much time wasted and just so many pounds sterling thrown away."
"What's that?" blustered the colonel. "What do you mean? What are you talking about? Tackbun Claimant? Who's the Tackbun Claimant? Do you realize to whom you are speaking? Fordyce, who and what is this infernally impudent puppy?"
"Gently, gently, Colonel. Name's Cleek, if you are anxious to know it."
"Cleek? Cleek?"
"Precisely, doctor. Cleek of Scotland Yard, Cleek of the Forty Faces, if you want complete details. And if there are more that you feel you would like to know, I'll give them to you when I hand you over to the Devonshire police for your part in this rascally conspiracy to cheat the late Lady Tackbun's nephew out of his lawful rights and to rot off the arm of the man who constitutes the living document which will clearly establish them. The lost Sir Aubrey Tackbun is dead, my friend, dead as Julius Cæsar, dead beyond the hopes of you and your confederates to revive even the ghost of him now. He died on a coral reef in the Indian Ocean five-and-twenty years ago, and the proof of it will last as long as Captain Bridewell can keep his arm and lift his voice to tell his story, and I think that will be a good many years, now that your little scheme is exploded. You'll make no X-ray martyr of that dear old man, so the money you spent in the instrument on the other side of that board partition, the thing whose buzzing you made him believe came from an electric fan, represents just so many sovereigns thrown away!"

"Yes, it was a crafty plot, a scheme very well laid indeed," said Cleek, when he went next day to the lych-gate to say good-bye again to Ailsa Lorne. "Undoubtedly a mild poison was used in the beginning, as an excuse, you know, for the 'colonel' to get him away and into the
