First appearance: the patient in room 18

At the inquest Gainsay admits he collided with Miss Keate near the porch, borrowed Dr. Letheny's car, and wired a message about an 'unexpected development' he will not discuss. His good-natured manner and half-amused smile sit oddly against the coroner's growing irritation and the wary look in his own half-closed eyes. Whether he is a suspect, a witness, or something else entirely, his refusal to explain himself makes him the most tantalizing figure in the early investigation.
