Christmas is coming, and the chocolate is off limits! When a massive snowstorm hits Fall Haven, many residents and out-of-towners alike are trapped out at the Old Maple Inn in the blizzard. Up-and-coming chef Won Shin prepares an extravagant French-Korean fusion meal as the inn's new chef-in-residence, and course after course, everyone gets a little more than they bargained for. But when someone turns up dead in a snowdrift right outside the inn, all signs point to a certain chocolate sauce as the likely culprit. Leigh and Paloma and the gang hunt down clues through cabins, kitchens, and the frozen wilderness to figure out who did the delectably dirty deed and why before someone else gets iced. With Arsenic Sauce is book 5 in the Wicked Wick Mysteries series.
