Lamie's restaurant at Hampton, New Hampshire, was announced as the destination of special detective Edward Glennon of the Cambridge police this morning, as the sleuth left to track down "the most promising clue" in the three-week-old disappearance of Sylvester Gardiner '46.

A night janitor employed there wrote to William T. Gardiner '14, the boy's father, yesterday, that he had collided with "a young man" whom he had seen before at 9:30 one evening last week. He thought nothing of it until he saw the pictures and description of Sylvester Gardiner definitely checked, the janitor added, recalling the cultured and apologetic manner of the youth.

William Gardiner, former governor of the state of Maine, declared he was highly encouraged by this tip yesterday. He said the family had stopped to eat at the roadhouse several times on route to their estates in Woolrich, Maine. His son might also have gone there, he continued, on route to the ski country.

Officer Glennon stated last night that he would have no trouble in recognizing Sylvester Gardiner on sight. While on duty during football games at Soldiers Field, he talked to the football center several times. "He was always very friendly to me," he recalled.

Relatives of Gardiner presented diverse explanations yesterday for his disappearance. One possibility still given credence was amnesia. His father noted his anxiety to row with the Varsity crew this spring, and thought that perhaps Sylvester resented the hastening of his graduation on GI credits which would make him ineligible to take his old position at stroke oar.
