A pawnbroker with blazing red hair brings Holmes an extraordinary story. He was selected for the Red-Headed League and paid handsomely merely to copy an encyclopedia. Then one morning he found an entirely unexpected notice on the office door. What will Holmes see behind this ridiculous affair?

In the autumn of 1890, Watson visits Baker Street and finds Holmes talking with an elderly red-haired gentleman. The visitor, a pawnbroker, produces a strange newspaper advertisement seeking men with vivid red hair for the Red-Headed League. At his assistant’s urging, he decided to apply for the mysterious vacancy.

Fleet Street is crowded with red-haired applicants, but Wilson’s extraordinary color wins him the position. Every morning he copies the Encyclopaedia Britannica and receives four pounds a week. The easy work continues for eight weeks, until he arrives one morning and finds a brief, astonishing notice fastened to the locked office door.

After Wilson leaves Baker Street, Holmes smokes his pipe in silence. He then takes Watson to Coburg Square, where the pawnbroker’s shop stands, and behaves in a puzzling way. The afternoon passes at a concert. As they part, Holmes warns Watson that danger will be waiting that night.

That evening, a police inspector and an unfamiliar gentleman are waiting at Baker Street. Guided by Holmes, the party travels by carriage through dark London. At their destination they extinguish the light and wait in silence. Watson still does not know whom they are pursuing or where Holmes solved the mystery.
