Miss Raffles: On account of an urgent business call, Mr. and Mrs. Leslie hurriedly close their summer home at Hudsoncliff and leave with their daughter, Jane, for the city. Bob, their son, decides to visit his parents at Hudsoncliff with his friend, Ralph Lyons. Bob and Ralph find the house locked up and, after some reconnoitering, enter through a window. Ralph hurts his ankle and is unable to attend a dance that evening, so Bob goes instead. Jane, on her arrival in the city, finds she has left her necklace in the safe at their summer home, and leaves a note for her mother, saying she is going back for it.
