Tannie Maria & the Satanic Mechanic — Sally Andrew

Everybody's favourite agony aunt and crime fighter Tannie Maria needs some counselling advice of her own. Lingering troubles from a previous marriage still sit heavy on her, while fresh worries about Slimkat, a local man whose fighting for his people's land threatens his life, keep her up at night.
Tannie Maria seeks out a counsellor, jokily known to all as “the satanic mechanic”. Straight out of The Rocky Horror Picture Show and from hot-as-hell Hotazel, Ricus fixes both cars and people.
But Maria's counselling tune-up switches gears when a murder flings her straight into Detective Henk Kannemeyer's investigation. Not only is she dating the dashing Henk, she now has to work beside him: a potential recipe for disaster.
Blending an intriguing mystery with characters as lovable as the setting of the rural Klein Karoo, this book is Sally Andrew's delightful, warm-hearted sequel to Recipes for Love and Murder.
