Conway Tearle’s third wife, Roberta Hill, filed for a divorce in 1917 after detectives she hired found him in a hotel room with Adele Rowland, a musical comedy actress and dancer. The two claimed they were just rehearsing a play as Rowland explained later, “As to the robe in which I was clad, it's the custom in the profession to read plays attired like that.”
The following February, Tearle and Rowland wed; remaining together until his death some twenty years later. Adele Rowland was the former wife of actor Charles Ruggles and was well known at the time for introducing to
