Once again I am grateful for the reviewer from Publishers Weekly who keeps alerting me to new puzzle mysteries published by Locked Room International. As an admirer of complexity for its own sake, I had much to enjoy in Szu-Yen Lin’s “Death in the House of Rain” which includes a character list as well as several house plans, diagrams, and charts, all of which are needed to keep track of what’s going on in Lin’s briskly paced “howdunnit.” Lin’s titular House of Rain is the scene of no fewer than four deaths in locked rooms as well as an earlier triple homicide. These are no ordinary run-of-the-mill killings, and I for one could hardly resist a book with a chapter titled “A Night of Beheading.” Readers who insist on plausibility in their fiction will no more appreciate this book than they would the contrivances of Rube Goldberg, but lovers of ingenuity and surprise will be well satisfied.
