But Cleek seemed not to take the slightest notice of him, and swinging upon his heel followed in the wake of the manager's broad back, while Wilson perforce had to return with Mr. Narkom. Half way up the stairs, however, Cleek suddenly stopped and gave vent to a hurried ejaculation.

"Silly idiot that I am!" he said, crossly. "I have left my magnifying glass on top of the safe—and it's the most necessary tool we policemen have. Don't bother to come, Mr. Brent, if you'll just lend me the keys of the vault. Thanks, I'll be right back."

It was certainly not much more than a moment when he did return, and the other members of the little party had barely reached the private office when he fairly rushed in after them. There was a look of supreme satisfaction in his eyes.

"Here it is," he said, lifting the glass up for all to see. "And look here, Mr. Brent, I've changed my mind about discussing the matter any further here. The best thing you can do is to go down in a cab with Mr. Narkom to the police station and get a warrant for this young man's arrest—no, don't speak, Mr. Wilson, I've not finished yet—and take him along with you. I will stay here and just scribble down the facts. It'll save no end of bother, and we can take our man straight up to London with us, under proper arrest. I shan't be more than ten minutes at the most."

Mr. Brent nodded assent.

"As you please, Mr. Headland," he said, gravely. "We'll go along at once. Wilson, you understand you are to come with us? It's no use trying to get away from it, man, you're up against it now. You'd better just keep a stiff upper lip and face the music. I'm ready, Mr. Narkom."

Quietly they took their departure, in a hastily found cab, leaving Cleek, the picture of stolid policemanism, with note-book and pencil in hand, busily inscribing what he was pleased to call "the facts."

Only "ten minutes" Cleek had asked for, but it was nearer twenty before he was ushered out of the side entrance of the bank by the old housekeeper, and though perhaps it was only sheer luck that nearly caused him to tumble into the arms of Mr. George Barrington—whom he recognized from the word picture of that gentleman given by Mr. Brent some time before—it was decidedly by arrangement that, after a few careless words on the part of Cleek, Mr. Barrington, his face blank with astonishment, accompanied this stranger down to the police station.

They found a grim little party awaiting them, but at sight of Cleek's face Mr. Narkom started forward and put a hand upon his friend's arm.

"What have you found, Headland?" he asked, excitedly.
