A Roderick Alleyn story, in Peter Wimsey vein. First rate yarn, with unusual set-up in murder of artist model in view of whole class, everyone of whom is suspect, and most of whom had the opportunity. Clues point hither and yon, but most of them to one man -- who is found murdered also. There's a romance throughout --and good background stuff. A sloppy piece of editing and proof-reading keep it out of the top class.
