PRIVATE OFFICE
NO ADMITTANCE.

One of the detectives tried this door and found it locked. Whereupon he placed his shoulder to it and prepared to force it in.

"Wait a minute," said Sturgis; "let me see if I cannot open it."

The detective stepped aside with a quizzical expression upon his face.

"I guess you will find it pretty solid for your weight," said he.

The reporter took from his pocket a piece of bent wire, and, with a few dexterous turns of the wrist, he shot the bolt of the lock.

"You would make an expert cracksman," said the detective. "I didn't know you possessed that accomplishment in addition to all your other ones."

The four men entered the private office. The room was quite dark, the shutters being closed and the blinds drawn. As their eyes became accustomed to the obscurity they were able to distinguish the outlines of a desk, a table, and a few chairs.

Sturgis went at once to a door in the corner. With the aid of his skeleton key he had soon thrown this open. After peering for an instant into the darkness, he took from his pocket a candle, which he lighted. Then, beckoning to his companions, he started cautiously to descend. The other men followed him and soon found themselves in the cellar, which they proceeded to search.

On the street side there was a recess extending for a few feet under the area in front of the house. The opening above was covered by an iron grating, over which was a wooden cover securely fastened on the inside by a chain and padlock. A number of carboys were carefully piled along the east wall to within a few feet from the rear of the building. Here, in the northeast corner, rose narrow shelving, on which were arranged a collection of bottles containing a varied assortment of chemicals.
