Londres, 1889. La hermana pequeą del cľebre Sherlock Holmes, Enola Holmes, ha decidido vivir sola a raz̕ de la repentina desaparicin̤ de su madre. Tras escapar de la vigilancia de sus hermanos, y al amparo de una identidad falsa, monta un gabinete como ±especialista en investigar todo tipo de desapariciones». Para su sorpresa, su primer cliente es el misms̕imo doctor Watson, que anda buscǹdola a ella pero por suerte no la reconoce. Enola no puede ayudar a Watson, pero se interesa por otro caso que ľ le menciona: la desaparicin̤, en los peligrosos bajos fondos londinenses, de la hija de un barn̤, Lady Cecily Alistair, una adolescente nada convencional...

Hiding from Sherlock and her other brother, Mycroft, who want to place her in a boarding school following their mothers disappearance, Enola has reinvented herself as Ivy Meshle, secretary to the fictitious Dr. Ragostin, specialist in finding missing persons. Her new client? None other than Sherlocks friend, Dr. John Watson! His mission: to employ Dr. Ragostin to find the missing Enola! She decides to take the case, only so she can keep tabs on Sherlocks every move to locate her. Yet Ivy Meshle is just one of Enolas disguises. In her search for a missing teenager, the Lady Cecily Alistair, she alternately poses as Lady Ragostin, wife of her non-existent employer, and as "Sister," the kindly nun who braves the dangerous nighttime alleys to bring comfort to the homeless. All the time she and Sherlock play a game of cat and mouse.
