Sign of Four

When Holmes is visited by a distressed young woman one dark night, he listens intently as she tells him of her father's disappearance ten years before and how, four years after his death, she began to receive a large and beautiful pearl once a year every year. Now she has a letter from the person who sent her the pearls: they wish to meet her.

Cand Holmes este vizitata de o tanara aflata in dificultate intr-o noapte intunecata, el asculta cu atentie cand ii povesteste despre disparitia tatalui ei cu zece ani inainte si cum, la patru ani dupa moartea sa, a inceput sa primeasca o perla mare si frumoasa o data pe an in fiecare an . Acum are o scrisoare de la persoana care i-a trimis perlele: vor sa o intalneasca.
