Denver Doll
 Denver Doll is a fictional character created by Edward Lytton Wheeler author of the Deadwood Dick dime novels. She originally appeared in four novels in Beadle's Half-Dime Library which were reprinted in the Deadwood Dick Library and in Aldine Boys' First-Rate Pocket Library in England.Denver Doll is considered by some scholars to be the first American female detective but copies of the first issue are so scarce that the conclusion eludes most researchers.
