You are the detective! Alone in his locked room (or was he?), Torrick the truckdiver succumbed, but to what, and why? Arthur, on his way downstairs for another drink, slipped, or did he? Siegfried Jones was obviously knifed on his way to the operating room, but by whom?
Lawrence Arthur Goldstone (1903 - 1998), better known by his pseudonym, Lawrence Treat, was an American mystery writer, a pioneer of the genre of novels that became known as police procedurals. A practicing lawyer before turning to writing, he was a founding member of the Mystery Writers of America and a two-time winner of the MWA's Edgar Award. His first award came in 1965, for the short story "H as in Homicide"; his second was a Special Edgar Award in 1978 for editing a new edition of the Mystery Writer's Handbook, the MWA's guide for aspiring mystery writers, first published in 1956.
As a member of the League of American Writers, he served on its Keep America Out of War Committee in January 1940 during the period of the Hitler-Stalin pact
Although I can see these "cases" which usually consist of about a paragraph of text and an accompanying drawing being used in a classroom setting, they could also be enjoyed by both children and adults. The objective is to read the short description of the case, view the drawing IN GREAT DETAIL and then answer 5 questions about the case, thus solving it. Answers and brief explanations to each case are located in the back of the book. Challenging pictures with minute details make it interesting even for adults. Kids love it.
