midnight
I know you picked up something in the flower bed : you refuse to tell me what it was . I know Miss Gertrude went back to the billiard-room to get something , she refuses to say what . You suspect what happened to the cuff-link , but you wo n't tell me . So far , all I am sure of is this : I do not believe Arnold Armstrong was the midnight visitor who so alarmed you by dropping -- shall we say , a golf-stick ? And I believe that when he did come he was admitted by some one in the house . Who knows -- it may have been -- Liddy ! '' I stirred my tea angrily .
