A Poison Of Passengers - Hilary Manningham-Butler, #4

"It's a bomb!" some fat idiot yelled, as I was heading for the exit. "They've found a bomb!"New York 1932. A letter bomb campaign throws the city into a panic and Hilary Manningham-Butler is anxious to get away. The RMS Galitia is setting sail for Southampton, but there will be no respite onboard ship. Another campaign is in the offing, less explosive but equally deadly. A series of anonymous letters are being distributed across the decks.
Someone knows far too much about the passengers in first class and venom is spewing in every direction. It will not be long before that venom spills over into violence and murder.
