That amiable Dutch detective duo from Outsider In Amsterdam, Grijpstra and de Gier, make their second appearance when a high class hooker turns up quite dead on her houseboat on the Schinkel. The victim, Maria van Buren, is a Curacao-born sorcerer with a green thumb for belladonna and nightshade. Her three regular customers are an influential lot each of whom has a perfect alibi. No magic, but light and affably baffling.
