The Rattle-Rat — Janwillem Van De Wetering

Douwe Scherjoen has been murdered, far from his native Friesland. This remote province of Holland is almost like a foreign country, so it's fortunate that Detective GrQpstra was born there. With Sergeant de Gier in tow, he heads across the dike to his homeland, where both officers interview a host of Frisians engaged in activities both legal and otherwise. The aging, gallant commissaris of Amsterdam's Murder Brigade puts in an appearance, and soon the mystery is solved--but not without the unexpected assistance of an asthmatic pet rat named Eddy.
