Rona Parish is continuing her series of articles on old family businesses when she learns that Curzon, local manufacturers of fine bone china, are about to celebrate their 150th anniversary. Furthermore, this is planned to coincide with the introduction of a revolutionary new line, about which there is much speculation. Rona decides to approach the firm, and almost at once is caught up in the intricacies of the Curzon family, little realizing that her involvement will directly precipitate a tragedy no one could have foreseen, a tragedy whose roots stretch back to George Curzon, son of the firm's founder, and known to his contemporaries as The Rogue in Porcelain.
