Mr Hill (The A.B.C. Murders)

In the novel The A.B.C. Murders, Mr Hill is a young man in Torquay. He went to the Palladium in Torquay and saw the film Not a Sparrow. While there he noticed a man acting strangely. The man was talking to himself, and Hill heard him say, "That's an idea." His description of the man was vague, but Inspector Crome felt that it linked up well enough with the descriptions of Alexander Bonaparte Cust, given by Mary Stroud and Tom Hartigan.
