Mrs Hook made her exit from a troubled world when her husband was about thirty years of age. As some compensation for her early departure she bequeathed him a legacy in the shape of a daughter, Sally, who, in addition to a pretty face and an excellent voice, possessed a remarkable aptitude for business. By force of her character and her shrewdness, plus her invention of a wonderful liqueur, Mr Hook eventually finds himself at the head of a thriving establishment and with a considerable fortune in the bank.
