The long shadow

This one finds Imogen as the two-month widow of vainglorious classics professor Ivor. She has no time to mourn him since she's so surrounded by living reminders--her charming, carefree stepson; her stepdaughter Dot, and Dot's husband and youngsters; her predecessor, Ivor's second wife; and a student in a burnous whose head emerges to accuse her, along with a young man, of killing Ivor. The story's not so much this time but then it's so amusingly beleaguered with the great man's left-behinds and they're all astutely observed.
