#13 Dog's Waiting Room

Amateur sleuth Steve Levitan and his clue-sniffing golden retriever Rochester face two deaths in the 12th full-length novel in this long-running series. An Alzheimer's patient slips away from home on his own and tumbles into the Delaware River. And then Steve's love Lili suffers the crushing loss of her mother in a Miami Beach hospital.

Eckhardt Lalor left behind a fortune in real estate, a fractured family, and a bitter legacy as a city slumlord. Does that add up to murder?

#14 Dog's Honest Truth

There's a new dog in town – a golden retriever named Luke, in training to be a seeing-eye dog. He and Rochester immediately bond, but there's something odd about Luke's human, Ben Ji. How can someone so young afford an expensive townhouse on Sarajevo Way? When Ben is shot, Steve begins to discover the lies he has been telling.

Steve's also forced to tell the truth about his past, when he deals with a student plagiarist at Eastern College, a professor locked in the stone age, a climate activist with dangerous habits, an angry bartender—and a rifle-wielding assassin.

#15 All Dog's Children

For semi-reformed computer hacker Steve Levitan, his long-time girlfriend, Lili, is acting out of character, and he's eager to figure out why and how he can help her. But that gets delayed when Steve and his golden Rochester are brought onto investigate a double homicide in a posh neighborhood of Stewart's Crossing.

As Steve and Rochester dig deeper, they find that the motive to kill the couple might have a far more disturbing origin, and catching the killer requires Steve to bend all of the rules as a semi-reformed hacker.
