Parul and her aunty Sutra are busy organising Donald and Michael’s weddings. When they are offered a weekend at a lodge just outside National Park on the Volcanic plateau by Sally, their next-door neighbour, both ladies decide to take advantage of the offer as a rest before the weddings. Before Parul leaves, she instructs Dolly Dennis and Parul’s new detective to look after the new agency. Dolly investigates the mystery urinator on Mrs Bagshot’s lawn and steps. While the two ladies are relaxing in the lodge, a murder is committed. There is a snow blizzard and everyone plus the murderer is snowbound in the lodge. Parul and Sutra try to investigate the murder. Parul is attacked and someone tries to strangle Sutra. Eventually, the snow clears. The National Park and Wanganui police try to locate the murderer. They flee over the snow drifts. Back at home, the ladies get on with the weddings, and a mysterious envelope arrives.
