I suppose it would be fitting to explain that I am talking into a dictaphone and the lovely Helen will be typing out my story for you to read. She will have a certain amount of creative control—sorting out moments when I get a bit tongue-tied or slightly muddled—but I have told her to leave in as much as possible, so as not to miss any of the important bits. This is my account of the Cavengreen Hotel murder, best we get that bit in early on.

The peaceful setting of Cavengreen Hotel has been shattered by a shocking murder. Hector Harrow, the hotel's concierge, has been accused and is determined to clear his name.
Hector enlists the aid of Helen, a retired publisher, to document the shocking crime that has unfolded, with the intention of publishing a truthful account.

Amid interruptions from a nosy journalist and the egotistical antics of the hotel's new owner, American Dave, Helen works tirelessly to keep Hector focused on finishing his book.

As suspicions fall on different guests and one makes a shocking confession, Hector must navigate a web of secrets to uncover the truth.
