In the latter, as may be remembered, Sherlock Holmes was able, by winding up the dead man's watch, to prove that it had been wound up two hours before, and that therefore the deceased had gone to bed within that time--a deduction which was of the greatest importance in clearing up the case.
Como se recordará, en este último caso Sherlock Holmes consiguió, dando toda la cuerda al reloj del muerto, demostrar que le habían dado cuerda dos horas antes y que, por lo tanto, el difunto se había ido a la cama durante ese intervalo... una deducción que resultó fundamental para resolver el caso.
