Dr. Dulcinea (Dulcie) Chambers is honored to have the esteemed British artist Logan Dumbarton as a guest at the Maine Museum of Art. The abstract expressionist painter has come all the way from London to teach a master class. His students, a group of talented local artists, are initially in awe. However, the eccentric artist is accompanied by an entourage that is proving less than ideal. His stunningly exotic wife Isabel is a constant distraction with her incessant whining, while Linda, Logan's ever-efficient sister and business manager, does nothing but placate her brother's whims. To make matters worse, Logan seems to vacillate between annoyingly sniveling and irritatingly egocentric at any given moment. Within a week the entire class loathes him. Is he really worth all of this trouble? Somebody doesn't seem to think so, and it's up to Dulcie to find out who. But she'll have to team up with Detective Nicholas Black once again, and at the moment their relationship can only be described as fragile.
