Arthur Conan Doyle

Yellow fog is swirling through the streets of London, and Sherlock Holmes himself is sitting in a cocaine-induced haze until the arrival of a distressed and beautiful young lady forces the great detective into action. Each year following the strange disappearance of her father, Miss Morstan has received a present of a rare and lustrous pearl. Now, on the day she is summoned to meet her anonymous benefactor, she consults Holmes and Watson.

In 1366, while England is at war with Spain, young Alleyne Edricson becomes a squire to Sir Nigel Loring and travels to France to join a bold band of archers known as the White Company.
