Schoolteacher Rosy Winter is dying. But beyond the homeopathic remedies, the dinner-party obligations, the snatched whispers on wards and in staffrooms, a force — murderous, feminine, feverish — is stirring within her. A story of power and powerlessness, light and dark, life and death, Mrs. Jekyll embraces the paradoxes and paroxysms of modern womanhood, in a story every bit as gripping as the original.
