A Tea by the Sea Mystery (Book 6)

Long ago, Lily's grandmother Rose worked as a kitchen maid at Thornecroft Castle, and now Elizabeth, dowager countess of Frockmorton, is celebrating her one hundredth birthday. Rose still has fond feelings for her onetime employer, so a group trip to Yorkshire is planned. Little do they know that Elizabeth plans to sell the famous Frockmorton Sapphires. The icing on the cake comes when the jewels suddenly vanish -- and things really go nuts when a party guest dies from an allergic reaction to almonds that someone smuggled into Lily's chicken sandwiches. Now she'll have to find out who would commit murder in such a manor.
