Lyle (Kyle Buchanan), the victim, seemed to have everything going for him when he met with Tess days before his murder. A recently tenured history professor, he was getting ready to propose to his girlfriend, Abby, via crossword puzzle when he came in deadly contact with a ceramic knife. Suspicion turns to her because she's a chef and has whole sets of cutlery with which to kill people.
But she's not the only suspect - there's a few of them in this smoothly-plotted mystery that benefits a lot from the two leads, their chemistry adds to this rather fetching addition to a great series. Love how the lead duo bump into a each other and Brennan asks her what she's doing and that she shouldn't investigate. You would have thought by now he would just allow to do what wants - after all she helped solve the other cases.
