In February 1917 Pearson acted in "The Professor's Love Story" before an audience at the Savoy Theatre. It was produced by H. B. Irving and featured George Arliss in the role of 'Professor Goodwillie'. Jeanne Eagels, then a very young performer, was among the players. The Belmont Theatre at 121 West 48th Street, New York City, staged "Penny Wise" in March 1919. Similar to "Bunty" in its theme, the setting of this play is Lancashire. It is a farcical comedy in three acts. Pearson performed the part of Rosa Dobbins. Critics considered this production lacking in both charm and humour when compared to "Bunty". The plot centred on a mother who attempted to collect life insurance on her son, who was "imperfectly dead". Pearson played the wife of the unfortunate son. Her role was somewhat secondary to that of her devious mother-in-law.
