Professor T

Professor T begins to work through his fears of the past and of intimacy with his therapist, while simultaneously helping solve a case in which all four members of a family are found dead by different means, with no sign of a struggle. 

Professor T is looking for an excuse to avoid giving oral exams, so he's eager to help Lisa and Dan investigate an apparent arson in a building full of students.

Lisa leads an investigation into threats on a wealthy but controversial businessman with an unusual family, while Professor T tries to avoid celebrating his birthday and the bad memories that come with it. 

A suspect has been apprehended in what appears to be a cut-and-dried murder case, but the daughter of the victim seems to know something more. Professor T tries to gain her confidence and learn the truth.

Professor T is characteristically blunt with the parents of a child who has been kidnapped, but quickly understands the complexity of the situation. 

While Professor T tries to avoid his mother, he ends up in the hospital as well as in the middle of a hostage situation, where he brings to bear some surprising rules that frustrate police officers as they attempt to save hostages. 

When someone is poisoned at a museum reception, the detectives again turn to Professor T for help in winnowing down the suspects, who include a woman who works at the university and has gossip swirling around her. 

While investigating a rape at her old college, Lisa Donckers decides to ask her former forensic criminology professor for help. Professor T is brilliant and knowledgeable, but also difficult to work with—and he has a history with Lisa's boss.
