From the Publisher:
Grijpstra and de Grier are called to an elegant townhouse where the body of a middle-aged woman has been found in her garden with a broken neck. The slippery steps - and the lady's drinking problem - make it look like an accident. But the dead woman's wealth, a neighborhood pet poisoner, and an ex-lover nicknamed "the Baboon" convince the commissaris that it's murder.
