Two murders, a strip club, and a Labradoodle. After the splashy success of her last big case, Olivia Lively, P.I., is struggling to manage Lively Investigations's sudden—and exciting—growth spurt. When an old friend offers her a chunk of cash to investigate his wife and brother who may be having an affair, Liv reluctantly agrees. She heads to a cozy cabin in the Maine woods to investigate, thinking it will be a chance to enjoy summer while also solving her cash-flow problem. When the suburban wife turns up dead, Liv discovers a possible connection to a seedy strip club and the Russian mob. It's a sticky summer in Portland, Maine, and in the heat of it all, Liv discovers that often the most complex relationship a woman has is the one with herself.
