Remembering the Dead by Elizabeth J. Duncan
Spa owner Penny Brannigan finds herself drawn into another mystery when the famous Black Chair awarded to Welsh poet Hedd Wyn goes missing during a dinner party at Ty Brith Hall. When one of the waiters is found dead and a local resident is injured, Penny and her circle of friends scour the party guest list for possible suspects and ponder who could possibly want the Black Chair for their own. Remembering the Dead is a great read-alike for the mysteries of M.C. Beaton.
