"Right through the closed door of a nine-inch concrete-walled vault, Wilson?" struck in Mr. Brent promptly. "Simmons had been shut in there by myself, Mr. Headland, and—"

"Shut in, Mr. Brent? Shut in, did you say? Then how did Mr. Wilson here, and the inspector enter?"

Young Wilson stretched out his hand imploringly.

"The door was open," he stammered. "I swear it on my honour. And the safe was open, and—and the notes were gone!"

"What notes?" It was Mr. Brent's voice which broke the momentary silence, as he realized the significance of the admission. For answer the young man dropped his face into his shaking hands.

"Oh, the notes—the £200,000! You may think what you like, sir, but I swear I am innocent! I never touched the money, nor did I touch my—Mr. Simmons. I swear it, I swear it!"

"Don't swear too strongly, or you may have to 'un-swear' again," struck in Cleek, severely. "Mr. Narkom and I would like to have a look at the vault itself, and see the body, if you have no objection."

"Certainly. Wilson, you had better come along with us, we might need you. This way, gentlemen."

Speaking, the manager rose to his feet, opened the door of his private office, and proceeded downstairs by way of an equally private staircase to the vaults below. Cleek, Mr. Narkom and young Wilson—very much agitated at the coming ordeal—brought up the rear. As they passed the door leading into the bank, for the use of the clerks, old Calcott came out, and paused respectfully in front of the manager.

"If you excuse me, sir," he said, "I thought perhaps you might like to see this."
