The Sentence Is Death by Anthony Horowitz

Eight years after one of three friends died during a caving expedition gone wrong, the other friends die within a day of each other. Hawthorne entices Horowitz into investigating the possible murders with him, as the basis of Horowitz 's second true crime novel based on Hawthorne's consulting work for the MET. The meta novel follows a similar recipe to its predecessor, but the whodunnit is definitely easier for the reader to figure out before the dénouement. There are some very clever homages to two lesser known Sherlock Holmes mysteries, which also adds to the enjoyment. Character development and self analysis is as always top notch. An engaging and entering read. 4/5
