Awesome / Whose Body?

• Lord Peter confronts the murderer under the guise of going for a medical examination. The murderer decides the best way to get rid of him is to inject him with poison. Lord Peter, who has spent the whole scene playing dumb, grabs and holds the murderer's arm away from him. He plays it off as him just being Afraid of Needles, but he knows the murderer knows he knows the truth.
• It's incredibly evil, but you must admit the crime is also remarkably clever: murder one man, then hide his body by substituting him for a dissection subject, which you then disguise and dump in a random house. Since no crime has been committed involving that particular body, it can't implicate you, while the other one has been dismembered and scientifically disfigured by eager medical students before being dutifully buried in a pauper's field where no one will look at it twice.
