Did You Know?


By the 1950s Mulford was no longer interested in writing any more Hopalong Cassidy novels. His publisher signed Louis L'Amour to write four books. After he signed, L'Amour found out the publisher wanted the William Boyd sanitized version of Cassidy instead of Mulford's rough-and-tumble version. L'Amour wrote the novels under the name "Tex Burns". See more »
