Thank you for sharing this information. As Mantan Moreland played such an important part in the Monogram portion of the Charlie Chan series, I think that such a book could be considered as something approaching "must read" status for fans of the detective. Is there much specific information relating to the Chan movies? Anecdotes, etc.?
Yes, the Chan films are given a separate chapter aside from Mantan's other pictures. His daughter Marcella (who was a child actress briefly) relates some anecdotes about the Monogram years. And some decent photos, too.
