It's a standing joke with crime writers that a visit to an exotic location should be followed by a book in the same setting, so that the trip can legitimately be treated as tax-deductible. It's also fair to say that writers who travel far and wide often feel inspired to transform their wanderings into fiction. A Mediterranean cruise features in my Forgotten Book for today, and I'm sure that the author, Freeman Wills Crofts, must have been on just such a cruise not long before he wrote the story.
One snag was that his trip, which included a stop in Cadiz, took place before the Spanish Civil War, and by the time Found Floating came out, he needed to explain in a prefatory note that the cruise undertaken by William Carrington and his family also pre-dated the conflict. But you can bet that Crofts enjoyed his cruise. He devotes a whole chapter to an account of the cruise ship! Even allowing for the fact that he did introduce some plot material as well, this "Interlude" as he describes it was a bit much, I felt. On the whole, the story is more about travel than the fairly ingenious murder plan at its heart.
William Carrington is a wealthy businessman, but there is a rift in the family about who should take over. His appointed successor, Mant Carrington, has recently come back to Britain from Australia, and he is not universally popular. He is the main target of an attempted poisoning, and the cruise is intended to aid the recovery of those who were affected, but Mant is not destined to return alive. Inspector French is given the chance to join the ship, and very pleased he is about it too.
The killer's scheme is quite complicated, but I must admit that French's unravelling of it did not keep me gripped. Part of the problem was the very small pool of potential suspects, and the fact that I didn't really care about them. Nor did I think that the killer's motivation was adequately signposted. Crofts wasn't very interested in criminal psychology, and this makes Found Floating a flawed book. He did much better in some of his other novels, but at least I'm sure he had a great time in the Med,!
