“Surely.  For instance, only the other day we had the cashier of the bank, Bolton Brown, arrested, though he is out on bail now.  We haven’t anything directly against him, but he is suspected of complicity on the inside, and I may say that the thing is so gigantic that there must have been some one on the inside concerned with it.  Among other things we have found that Bolton Brown has been leading a rather fast life, quite unknown to his fellow-officials.  We know that he has been speculating secretly in the wheat corner that went to pieces, but the most significant thing is that he has been altogether too intimate with an adventuress, Adele De-Mott, who has had some success as a woman of high finance in various cities here and in Europe and even in South America.  It looks bad for him from the commonsense standpoint, though of course I’m not competent to speak of the legal side of the matter.  But, at any rate, we know that the insider must have been some one pretty close to the head of the By-Products Company or the By-Products Bank.”

“What was the character of the forgeries?” asked Kennedy.

“They seem to have been of two kinds.  As far as we are concerned it is the check forgeries only that interest the Surety Company.  For some time, apparently, checks have been coming into the bank for sums all the way from a hundred dollars to five thousand.  They have been so well executed that some of them have been certified by the bank, all of them have been accepted when they came back from other banks, and even the officers of the company don’t seem to be able to pick any flaws in them except as to the payee and the amounts for which they were drawn.  They have the correct safety tint on the paper and are stamped with rubber stamps that are almost precisely like those used by the By-Products Company.

“You know that banking customs often make some kinds of fraud comparatively easy.  For instance no bank will pay out a hundred dollars or often even a dollar without identification, but they will certify a check for almost any office boy who comes in with it.  The common method of forgers lately has been to take such a certified forged check, deposit it in another bank, then gradually withdraw it in a few days before there is time to discover the forgery.  In this case they must have had the additional advantage that the insider in the company or bank could give information and tip the forger off if the forgery happened to be discovered.”

“Who is the treasurer of the company?” asked Craig quickly.

“John Carroll—­merely a figurehead, I understand.  He’s in New York now, working with us, as I shall tell you presently.  If there is any one else besides Brown in it, it might be Michael Dawson, the nominal assistant but really the active treasurer.  There you have another man whom we suspect, and, strangely enough, can’t find.  Dawson was the assistant treasurer of the company, you understand, not of the bank.”
