Her forehead gathered into little furrows; and, reverting to the code message, her thoughts harked back to a well-known crime, the authorship of which still remained a mystery, and which had stirred the East Side some two years ago. A man - in the vernacular of the underworld a "stage hand" - by the name of Kroner, credited with having a large amount of cash, the proceeds of some nefarious transaction, in his possession on the night in question, was found murdered in his room in an old and tumble-down tenement of unsavory reputation. The police net had gathered in some of the co-tenants on suspicion; Nicky Viner, referred to in the code message, amongst them. But nothing had come of the investigation. There had been no charge of collusion between the suspects; but Perlmer, a shyster lawyer, had acted for them all collectively, and, one and all, they had been discharged. In what degree Perlmer's services had been of actual value had never been ascertained, for the police, through lack of evidence, had been obliged to drop the case; but the underworld had whispered to itself. There was such a thing as suppressing evidence, and Perlmer was known to have the cunning of a fox, and a code of morals that never stood in the way, or restricted him in any manner.
The code message threw a new light on all this. Perlmer must have known that old Nicky Viner had money, for, according to the code message, Perlmer prepared a fake set of affidavits and forged a chain of fake evidence with which he had blackmailed Nicky Viner ever since; and Nicky Viner, known as a dissolute, shady character, innocent enough of the crime, but afraid because his possession of money if made public would tell against him, and frightened because he had already been arrested once on suspicion for that very crime, had whimpered - and paid. And then, somehow, Danglar and the gang had discovered that the old, seedy, stoop-shouldered, bearded, down-at-the-heels Nicky Viner was not all that he seemed; that he was a miser, and had a hoard of fifty thousand dollars - and Danglar and the gang had set out to find that hoard and appropriate it.
Only they had not succeeded. But in their search they had stumbled upon Perlmer's trail, and that was the key to the plan they had afoot to-night. If Perlmer's fake and manufactured affidavits were clever enough and convincing enough to wring money out of Viner for Perlmer, they were more than enough to enable Danglar, employed as Danglar would employ them, to wring from Nicky Viner the secret of where the old miser hid his wealth; for Viner would understand that Danglar was not hampered by having to safeguard himself on account of having been originally connected with the case in a legal capacity, or any capacity, and therefore in demanding all or nothing, would have no cause for hesitation, failing to get what he wanted, in turning the evidence over to the police. In other words, where Perlmer had to play his man cautiously and get what he could, Danglar could go the limit and get all. As it stood, then, Danglar and the gang had not found out the location of that hoard; but they had found out where Perlmer kept his spurious papers - stuffed in at the back of the bottom drawer of his desk in his office, practically forgotten, practically useless to Perlmer any more, for, having once shown them to Viner, there was no occasion to call them into service again unless Viner showed signs of getting a little out of hand and it became necessary to apply the screws once more.
For the rest, it was a very simple matter. Perlmer had an office in a small building on lower Sixth Avenue, and it was his custom to go to his office in the evenings and remain there until ten o'clock or so. The plan then, according to the code message, was to loot Perlmer's desk some time after the man had gone home for the night, and then, at midnight, armed with the false documents, to beard old Nicky Viner in his miserable quarters over on the East Side, and extort from the old miser the neat little sum that Danglar estimated would amount to some fifty thousand dollars in cash.
