Love is a many murdered thing. Three months after catching a killer, Margarita escapes to a historic hotel with Drew and Bindi for a Valentine's weekend of geocaching. But during the love-themed costume ball, the CEO of a satellite navigation company keels over-and then his body vanishes. As the weekend progresses, Margarita discovers threatening messages in the logbooks of local geocaches. Her attempts to unmask the blackmailer are thwarted by the last person she would have expected. With a stubborn sheriff on the case, Margarita and Bindi must take matters into their own hands. But whether they're chasing one killer or two, they have a problem: all their suspects seem to have solid alibis. Between misunderstandings, outright lies, old secrets, and more than one corpse, it's not Love in the air anymore. It's Death.
