"You have done right," cried Dyke Barrel. "Have you opened the satchel?"

"No. It is locked, and I haven't a key that will fit."

Harry Bernard produced several keys, none of which fitted the lock to the satchel.

"What are we to do?" cried Bernard. "The satchel is securely locked, and its owner has the key."

"This is no time for ceremony or undue squeamishness!" uttered Dyke Darrel. "We are on the eve of an important discovery, and I propose to make no delays."

Then, drawing a knife from his pocket, the detective bent over the satchel and slit the sides at one stroke.

"That will open it if a key won't," he remarked, with grim satisfaction.

The contents of the satchel were a revelation.

Red wigs and a complete suit of clothes, besides paints and powders.

Harry uttered an exclamation.
