Clarke Van Dyke was an actor who introduced himself to Dick Tracy immediately following Tracy’s adventure with B-B Eyes. Van Dyke was a dark-haired man with light eyes, and a Van Dyke-style beard and moustache. Van Dyke reported the disappearance of his fellow actor, Yollman, who was playing the lead in a production of “Blue Flame” at the Auditorium Theater. Yollman’s wife Dianne was the leading lady and Van Dyke was his understudy. Yollman had disappeared without a trace and Dianne had asked Van Dyke to contact Tracy to investigate.
