THE MEMORY OF BLOOD : a Peculiar Crimes Unit mystery

"When a murder at a drama company's cast party thrusts them into London's theater underground, Arthur Bryant and John May investigate a neurotic director, a jealous theater owner, a deranged playwright, and a terminally rude critic."@en
"The indomitable duo of Arthur Bryant and John May, along with the rest of their quirky team, must solve a confounding case with dark ties to the British theater and a killer who may mean curtains for all involved."
"For the crew of the New Strand Theatre, the play "The Two Murderers" seems less performance than prophecy when a cast party ends in the shocking death of the theater owner's son. The crime scene is most unusual, even for Bryant and May. In a locked bedroom without any trace of fingerprints or blood, the only sign of disturbance is a gruesome life-size puppet of Mr. Punch laying on the floor. Everyone at the party is a suspect, including the corrupt producer, the rakish male lead, the dour set designer, and the assistant stage manager, who is the wild daughter of a prominent government official."@en
