A new case for the ladies of the WISE enquiries agency . . . Henry Devereaux Twyst, eighteenth Duke of Chellingworth, is terribly worried about some water damage to the priceless books in his lower library, so retains the services of a local book restorer to tackle much-needed repairs. The antiquarian also runs the Crooks and Cooks bookshop with his daughter - local TV celebrity chef, The Curious Cook. When the book restorer mentions some strange shenanigans going on at the book shop, Dowager Duchess Althea brings the case to her colleagues at the WISE Enquiries Agency. As the WISE women try to unravel one puzzle from their base at stately Chellingworth Hall, they then get embroiled in another when they come across a valuable book of miniatures which seems to be the work of a local famous artist, murdered by her own brother. Are the cases linked and why do both mysteries lead to a nearby old folks' home? The WISE women are on the case - and nothing will get in their way . . . Or will it?
