AC - DUMB WITNESS

Dumb Witness allowed Agatha Christie to indulge in her love of dogs. She had always had a dog since a young age and was incredibly fond of them, and Bob is directly inspired by her own pet. The book is actually dedicated to Agatha Christie's own wire-haired terrier Peter; "A dog in a thousand". This story also contains the penultimate appearance of Hastings, with several references to earlier cases including Murder on the Orient Express and Death in the Clouds.
