Pearl's detective agency takes a back seat as she prepares to offer a warm welcome to a group of special visitors. A local Arts Festival is being held to honour a cultural exchange visit from representatives of Borken, Whitstable's Twin Town in Germany. Yet very soon, personality clashes surface among the participants; local politicians try to use the festival for their own ends while others jostle for improved billing on the festival programme. Tempers flare, old feuds re-surface and on the eve of the first event, a cryptic message, Murder Fest, is received by the local police. Before DCI Mike McGuire has a chance to investigate, the festival commences with an unscheduled event when a celebrated author is found brutally murdered. Soon the only 'Arts' on display are dark ones, as Whitstable's celebration of local culture transforms into a real-life murder fest, offering Whitstable's Pearl Nolan another mystery to solve.
