Scents and sensibility [Playaway]
(Playaway)

Private Investigator Bernie Little and his canine companion Chet return home to encounter some alarming developments. First off, Bernie's wall safe--normally hidden behind the waterfall picture in the office--is gone, and with it Bernie's grandfather's watch, their most valuable possession. And next door, old Mr. Parsons is under investigation for being in possession of a saguaro cactus illegally transplanted from the desert. Bernie and Chet go deep into the desert to investigate. Is it possible that such a lovely old couple have a terrible secret in their past? Chet and Bernie discover bad things going on in the wilderness, far worse that cactus smuggling, and all connected to a strange but innocent-seeming desert festival called Arrow Bright. They unearth leads that take them back to a long-ago kidnapping that may not have been a kidnapping and threaten a ruthless and charismatic criminal with a cult following, a criminal who sees at once what Chet and Bernie mean to each other and knows how to exploit it.
