Fergus Hume (Ferguson Wright Hume, 1859–1932) was one of the pioneers of the detective genre. His most famous book, "The Mystery of the Black Cap," inspired A. Conan Doyle to write the Sherlock Holmes novel "A Study in Scarlet." Born in England, he studied law in New Zealand, then moved to Australia, traveled extensively, and wrote about one hundred and forty novels.
Daisy Kent receives an anonymous letter with threats on the eve of her engagement being announced—and the next day the girl is found stabbed with a dagger in a churchyard cemetery.

But Anna suddenly disappears, and proving both her guilt—and her innocence—becomes extremely difficult; and to make matters worse, a mysterious "Crimson Cross" is involved in the case…
Daisy’s fiancé, Giles Veyr, sets out to solve this mystery.
