The stark naked body was lying in the tub. Not unusual for a proper bath, but highly irregular for murder — especially with a pair of gold pince-nez deliberately perched before the sightless eyes. What’s more, the face appeared to have been shaved after death. The police assumed that the victim was a prominent financier, but Lord Peter Wimsey, who dabbled in mystery detection as a hobby, knew better. In this, his first murder case, Lord Peter untangles the ghastly mystery of the corpse in the bath
Considering this is the first in the series, Wimsey (plus Bunter, plus the Duchess) are strong characters already, with Wimsey being presented with a dead body in a bathroom, whilst the police are investigating the disappearance of Sir Reuben Levy, a financier who disappeared whilst on a night out.
It’s fairly evident the significance of the unidentified body, but it’s just a case of proving it. The written confession unfortunately, comes late in the book, and is all but redundant, as the reader should have worked it all out for themselves by the time it comes out (and it’s all done bar the shouting).
