Detective Inspector Jake Talbot has been having a bad year. He's spent most of it investigating a truly horrendous crime. It's finally resolved, but during it, his significant other, Claire, got tired of it and him and moved out, taking not just all her own things, but gifts she'd given him. It's now nearly Christmas, always a bad time of year for him because of a past family tragedy--but worse than ever this year, because of the Lassiter case and Claire's departure.
Not wanting to take his boss's advice and take time off, Jake focuses instead on what seems to be a minor case, easily resolved: A young man unrelated to the family has been attempting to visit Lillian Charteris in her care home, over the objections of her grandchildren, Peter and Melanie Charteris.
Yet the young man, Frankie Hayward, seems quite harmless, and Peter's reaction, in particular, seems out of all proportion and entirely too personal.
