 What is the most likely reason why Tremaine confides in Jess about the case?
In his room at the Elsby Commercial Hotel, Tremaine opened his luggage and took out a small tool kit, used a screwdriver to remove the bottom cover plate from the telephone. Grammond's boys are supposed to keep me informed. Project Officer for the hyperwave program—he's been on my neck day and night.

Tremaine left the hotel, walked two blocks west along Commerce Street and turned in at a yellow brick building with the words ELSBY MUNICIPAL POLICE cut in the stone lintel above the door.

I used to think she was some kind of princess...." "What about her and Bram? Miss Linda was maybe in her twenties—and that made her an old maid, in those times. Now, you know Bram was funny about any kind of socializing; never would go any place at night. Just before sundown they went off together in that fancy shay. "After dark.
