 Why did Jimmy Tremaine visit his hometown?
He was as ancient as time—and as strange as his own frightful battle against incredible odds! 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. He inserted a tiny aluminum cylinder, crimped wires and replaced the cover. Then he dialed a long-distance Washington number and waited half a minute for the connection. Grammond's boys are supposed to keep me informed. You elected me to be a leg-man: now let me do it my way."

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. "Jimmy," he said, "Jimmy Tremaine." In a back room Tremaine said, "To everybody but you this is just a visit to the old home town. Between us, there's more." Tremaine covered the discovery of the powerful unidentified interference on the high-security hyperwave band, the discovery that each transmission produced not one but a pattern of "fixes" on the point of origin. It showed a set of concentric circles, overlapped by a similar group of rings. "I think what we're getting is an echo effect from each of these points of intersection. The rings themselves represent the diffraction pattern—" "Hold it, Jimmy. "The point is this, Jess: we think we've got it narrowed down to this section. This is where I should come up with the news that Old Man Whatchamacallit's got an attic full of gear he says is a time machine. Trouble is, folks around here haven't even taken to TV. "Course," said Jess, "there's always Mr. Bram ..." "Mr. Bram," repeated Tremaine. Comes in town maybe once a week, buys his groceries and hikes back out to his place by the river." "I always liked him. "I've never seen any harm in Bram," said Jess. You remember old Aunt Tress, used to know all about ancestors and such as that? She used to say he'd lived in that same old place out on the Concord road when she was a girl.
