The Milk Tart Murders (Tannie Maria Mystery #4)

Who knew a Marilyn movie could kill you? When Oom Frik of Oom Frik's Fantastiques dies during a vintage movie screening in Ladismith, Tannie Maria and her policeman boyfriend Henk are on the scene.
Ja, the old thrift-shop owner had a heart condition, but was there more to his demise? It's rumoured that among Frik's junk are valuable treasures, and the grumpy, paranoid old guy frequently altered his will.
When a second body turns up, there's a clue: a letter addressed to Tannie Maria asking for advice - and a milk tart recipe. Fifty-plus agony aunt Maria and feisty young journalist Jessie conduct their own treasure hunt and murder investigation. The police are looking for the perpetrator too, but the amateur detectives have unique skills, and Tannie Maria's food is a powerful incentive to get people to talk.
Maria and Jessie step into deep danger, but all is not doom and gloom. Spring has arrived in the Karoo, and Henk and Maria discuss moving in together, even though his home is still full of his late wife's stuff. Maria knows food has a way of filling the dark spaces, for the better or for the worse. Perhaps, once the Klein Karoo crime-buster's work is done, she might follow her own advice and try a healing recipe.
