Professor T - PBS

After Season 3’s shocking finale, Dan and Jasper are consumed by grief. Dan throws himself into work while the Professor hides in his lectures, avoiding the police at all costs. But Helena, Jasper’s therapist, helps him face back up to his police work and the team tackles complex and dangerous cases. But through the danger and mystery, love is very much in the air.

Professor T is available to stream on pbs.org and the PBS app.

Professor T is in jail awaiting trial. The hostile, dirty and noisy environment plays havoc with his OCD, plus he is a curiosity among the inmates. But his brilliant criminal mind will soon be put to good use by some of the less than brilliant criminals he finds himself surrounded by.

Professor T is based on the hit Belgian series of the same name.

While Professor T struggles to get his old life and job back, he is helped by Dan and Lisa who again rely on his incisive criminal insight and analysis to solve some tricky and intriguing crimes.

Professor Jasper Tempest and the team untangle a series of knotty crimes ranging from an unexplained fire in a student block to the mystery of an entire family found dead in their home. Meanwhile, Professor T is dominated and perplexed by the women in his life, from his mother to the love of his life Christina, and his new therapist, Dr. Helena.

Every aspect of Professor Jasper Tempest's life is precisely calibrated and rigidly structured. Impeccably dressed and meticulously punctual, he lectures daily at the Cambridge Institute of Criminology, teaching students imaginatively, if pedantically, about the science of crime. Each evening, he returns home to his apartment, which is as sterile and systematically ordered as a science lab.

But Professor T's buttoned-down world is slowly undone when he is persuaded by one of his former students, Detective Sergeant Lisa Donckers, to assist her in investigating a difficult case. The professor's encyclopaedic knowledge of criminal psychology and his brilliant mind prove invaluable to the under-resourced CID team, but the cracks in his carefully constructed emotionless carapace also begin to show.
