Take Sherlock Holmes, House, and Monk, put them in a blender and have them speak Flemish, and you have Professor T. This popular Belgian show is coming to PBS May 2nd. You will have to check local listings to find out when your station will carry it. However, if you have PBS Passport, the whole series will be available to stream May 2. Seems audiences will never get enough of eccentric grouches who solve mysteries (medical or criminal). Note that this is the original Professor T. It has been remade in French and German, but I am referring to the Belgian one here.
