November 1933. Amateur sleuth-cum-dutiful granddaughter Kitty Underhay stifles a sigh of boredom as she attends the annual Hoteliers’ Association Dinner and Dance on behalf of her grandmother, the proprietress of the Dolphin Hotel. She hopes the company of ex-army captain Matthew Bryant will enliven the otherwise dull evening. That is, until bullish and overbearing local councillor Harold Everton drops dead into his bowl of consommé. While the local police are still scrambling for their whistles, Kitty and Matt waste no time leaping into action. Soon they find themselves caught up a dangerous search to uncover who amongst the distinguished guests used cyanide for seasoning?
