"We shall start on our hunt at once, eh, Hamington?"

"Certainly. But let us take a look around the office first. And, Mr. Sumner?"

"Well?"

"It might be just as well to keep this matter a secret for a few days. Of course, information will be sent out from headquarters, but the general public need not know of it."

"That will suit me," returned the elderly broker, with a groan. "If the word gets out it will all but ruin me. I only held the bonds in trust, and will be expected to make the loss good in case they are not recovered."

"You will give us a list of the paper?"

"Certainly." Mr. Sumner took out a memorandum book. "Here you are. Anything else?"

"We will take a look around the premises."

And the two detectives started on a tour of investigation, in which Hal took a lively interest.

The door to the safe was carefully examined. Not a mark was found upon it.
