<P> Crime runs rampant in the picturesque town of Leixleap -- and onIreland's famed River Shannon, where brazen thieves illegally harvestthe gourmet-prized eels that flourish there. But while poachingmay be something the local Eel Police division is well-equippedto handle, murder is wholly another matter.</P. <P>Chief Inspector Peter McGarr has been called out from Dublin to investigate a troubling double homicide. The nude body of young, pretty, and,recently married Eel Policewoman Ellen Gilday Finn has been discoveredin the bed of a hot-sheet inn -- wrapped around the equally unclothedcorpse of her much older boss, Pascal Burke. A crime of passion, perhaps, pointing to Ellen's cuckolded newly wedded husband as the perpetrator.
