From Here to Paternity — Jill Churchill

Jane Jeffry, suburban sleuth extraordinare, and her friend, Detective Mel VanDyne, have braved a blizzard to join her friend Shelley at a Colorado ski resort. In spite of having all their kids along, Jane and Shelley imagine a few mindless days of relaxation. But their hopes are dashed on their first attempt to ski when Jane careens into a snowman that hides a very real -- and every dead -- body.

The slopes are littered with suspects -- a convention of genealogists led by a political fruitcake who thinks she's going to put her hand-picked Tsar on the Russian throne, a mysterious crimson-clad skier who's always on the horizon, and ex-stockbroker who's hiding from his investors, and an irate tribe of Native Americans. Jane has to take a census of the suspects and make some grave assumptions about who was vacationing with malicious intent.
