"The Streetbird" is titled after a vulture de Grier at the scene of a crime in the red light district. There should be no vultures in Amsterdam, but neither should there be murders. This particular murder victim was a pimp: unmourned by his ladies, feared by his rivals and despised by the authorities - and now only a police matter to be disposed of with typical Dutch tidiness. Reluctantly, Rinus de Gier, still looking for love, Grijpstra (whose awful wife has at last left him) and the arthritic and wise Commissaris try to unravel a particularly unsavory business, which ultimately leads them by different paths to a denouement infinitely more shocking than the crime itself.
