This novelet features Don Quebranta Huesos, a grim Spanish criminal who is "vicious toward the rich and evil but kind to the poor and good" (Steinbrunner and Penzler). Don Q. may have helped inspire Johnston McCulley's "Zorro" character. Indeed, there are so many similarities that Douglas Fairbanks turned the Don Q. character into the film sequel to The Mark of Zorro—as Don Q., Son of Zorro—in 1925.
