Murder on the English Coast

In the third installment of the Four Queens of Crime mystery series, DCI Lilian Wyles is settling into retirement by the sea, until a murder derails all her plans.1949, England. After thirty years of service, DCI Lilian Wyles is happily retired on the English coast. Launching a new life adventure, she now co-owns a guesthouse in Torquay with her best friend Elspeth.  Meanwhile, Ngaio Marsh is finally returning to England after ten long years, and Agatha Christie has the clever idea to host a week-long reunion for the four queens of crime at Lilian's guesthouse.
With the arrival of Dorothy L. Sayers, Margery Allingham, and Lilian's former colleague DCI May Lee, the group is a full house. The reunion celebration starts off brilliantly, until they stumble upon a body and realize that the guesthouse may be central to a local murder. Meanwhile, town gossip has labelled the guesthouse cursed, and they begin to experience mysterious incidents that validate the rumors.
When Lilian's former CID partner, Richard Davidson-currently in MI5-joins the crew, he admits he's on the job, tracking enemy agents he suspects are being smuggled into England nearby.  With an escalating threat of a new invisible war-the race for the Bomb-this seemingly innocent-looking seaside town is now ominous. Full of potential murder suspects, enemy agents, and international intrigue, this quiet holiday will turn into the highest-stakes mission the group has ever faced.
