Carlotta Carlyle has just returned home when a dead woman walks through her door. Manuela Estefan is breathing, walking, and talking- but according to the newspaper in her hand, she was just found savagely murdered in a marshy park not far from Fenway. The deceased woman was carrying Manuela's ID card, and Manuela now begs Carlotta to get it back. Boston PIs aren't supposed to touch murder cases, but when Carlotta comes back from the kitchen with a glass of water, Manuela has vanished, leaving five crisp hundreds on the table as a silent plea for help.
