Murder 101 is the name of a series of four made-for-television mystery films 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.
