The third part from the tetralogy "the secret of Sally Lockhart". Sally Lockhart is a young ambitious girl who lives in England at the end of the XIX century. But she is not a modest, spoiled young lady of the Victorian era. Sally famously rides a horse, shoots a pistol without missing a beat, and is adept at doing business. In the novel Tiger in the well, the heroine needs all her courage and natural intelligence to confront a ruthless opponent who has emerged from the past and haunts her like a ghost from a nightmare.
