Dorothy Dixon and the Double Cousin

Dorothy, a resourceful young investigator, becomes embroiled in a family mystery when a cousin’s identity and safety come into question. Assisted by a detective and several friends, she stages covert observations and a daring rooftop descent to reach a locked city flat, then follows clues through surprises, tests, and revelations. Elements of disguise, sleepwalking incidents, canine help, and holiday gatherings complicate the inquiry, while small practical tricks and steady reasoning expose imposture and hidden motives. The narrative balances puzzle-solving with camaraderie as the group pieces together evidence and resolves the tangled relationships at the heart of the case.
