Summer in the Lincolnshire Wolds and Clarice is rung by her friend Louise, asking whether she can look after Susie, her son's lively Boxer, as 41-year-old Guy has gone missing from the family home. His mother thinks he has been suffering from depression but more worryingly, in his professional life, he had been working on a high-profile case, defending a known criminal. His home life was beset with problems too, which is why his mother has asked Clarice to look after the dog; Charlotte, Guy's wife, just can't cope with her as well as their three daughters.
Getting drawn into the puzzle of Guy's disappearance, Clarice wonders how Susie received a nasty cut to her back leg, and who is the mysterious Charles? Guy apparently did not trust him enough to let him into his home, and he had not been seen since he was driven away in Charles car. Guy's friends all say that he was a good, honest man, but as Clarice looks further into the murky criminal world he inhabits, she questions if Guy has been pulled in out of his depth. And - why does Susie keep returning to the private woods, where she had spent so much time with her beloved master....
