Jadwin did not go directly into Gretry’s main office, but instead made his way in at the entrance of the Board of Trade Building, and going on past the stairways that on either hand led up to the “Floor” on the second story, entered the corridor beyond, and thence gained the customers’ room of Gretry, Converse & Co. All the more important brokerage firms had offices on the ground floor of the building, offices that had two entrances, one giving upon the street, and one upon the corridor of the Board. Generally the corridor entrance admitted directly to the firm’s customers’ room. This was the case with the Gretry-Converse house.

Once in the customers’ room, Jadwin paused, looking about him.
