It began as a student exercise; the knife under the drape, the model's pose chalked in place, but before Agatha Troy, artist and instructor, returns to the class the pose has been re-enacted in earnest. It's a difficult case for Inspector Alleyn. He loves Agatha but no one can be above suspicion. Police procedural.
