The usual mix of murder and robbery for Lt. Luiz Mendoza's L.A.P.D.--with one intriguing puzzle threading its way through the overlapping cases. That beguiling mini-plot: the Mendozas, returning from a European vacation, sit next to young Frenchwoman Juliette Martin, who's looking forward to a reunion with her long-estranged grandfather in California; later, in L.A., Mendoza recognizes Juliette--as a suicide, supposedly named Ruth Hoffman (!), in a decrepit building; and it takes a trip to Paris, with help from a French counterpart, before Mendoza uncovers the complex doings behind this enigma. Meanwhile, the trusty L.A.P.D. team is dealing with the gamut of mayhem: the murder of an old, cancer-ridden hospital patient, smothered by a pillow; an elderly black woman found dead in her apartment behind the variety store she owned (her killer is traced by good lab work); and much, much more. An above-average Mendoza-thon, in short--and Shannon keeps it all spinning with crisp, professional ease.
