Dear Detective,

Surely you have seen the papers and read about the dreadful murder of the American novelist—stabbed while in a room with six other people, and yet no one went near him or saw the murder occur. The crime is so devious, so logistically impossible, that it seems to have been committed not by a person but by a disembodied hand.

I must confess that we are at a loss. Who wrote the poison pen letters that lured these seven people to this deadly gathering? A poet, an earl, an actress, a cook, a telephone operator, and a lothario . . . What do they have in common? And how could a man be stabbed in a room full of suspects, even though no one went near him or saw a thing?

We have had our best people on the case, Detective, and we still can’t make heads or tails of it. We are giving this case file to you. Can you decipher the clues, decode the witness statements, and identify the murderer? You are our last hope. Can you help us crack the Creeping Hand Murder?

Yours truly,
Detective Chief Inspector of the Metropolitan Police
