When vivacious man-eater, Maria Marshall is found dead in her locked room, there's a gallery of suspects at the Kinging Guest Lodge. An amateur astronomer. A tortured artist. An ebullient preacher. The guesthouse owner. His long-suffering wife. A faded sports hero cum recovering drug addict. And Mrs. Marshall, Maria's own mother! With her razor sharp wit, acerbic tongue and sharp knitting needles, wheelchair-bound Mrs. Marshall always provokes a reaction. There's also Alex Simpson, a retired police officer who comes to Kinging for the home-cooked meals and serene environment. But on his last visit, another young woman was found dead in the same room as Maria... So, who in this cozy mystery, has a strong enough motive and ample opportunity to not just murder Maria at midnight, but also have her door locked from inside?
