A very nervous man named Cartwright comes into Perry's office to have the neighbor arrested for his howling dog. He states that the howling is a sign that there is a death in the neighborhood. He also wants a will written giving his estate to the lady living at the neighbors house. It is all very mysterious and by the next day, his will is changed and Cartwright is missing, as is the lady of the house next door. Perry has a will and a retainer and must find out whether he has a client or a beneficiary.
