Murder 101 is the name of a series of four TV movies released by the Hallmark Channel between 2006 and 2008, and now appearing regularly on the Hallmark Movie Channel. They starred Dick Van Dyke and his son Barry Van Dyke. It may look like a continuation of Diagnosis Murder, but Barry instead plays the son of an old friend of his father's character; there are some other differences. While on the Hallmark Channel, it was broadcast in rotation with the movie series McBride, Mystery Woman, and Jane Doe, under the umbrella title Hallmark Channel Mystery Wheel. In the UK, these movies are aired, on a rotation basis, in the afternoon drama slot on channel 5.
