 Who was in the black sedan that rushed off past Tremaine a block from the hotel?
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. 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. 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 was ten minutes before he beckoned Tremaine over to the table where a two-foot-square book lay open. Vice-President Roosevelt had made a speech.
