King of the Mountain

I only know M.K. Wren from reading her post-apocalyptic novel, A Gift Upon the Shore, so was surprised to find that she has a whole series of mysteries with a PI protagonist named Conan Flagg. Flagg also owns a bookstore on the coast of Oregon, and he is loathe to leave it just now, but his friend, Lise King, has pleaded with him to join her family for her father's annual birthday get together at his lodge in the mountains east of Portland. The trip brings together wealthy timber man A.C.King, his relatively new and much younger wife, and his 3 sons, at least two of whom appear to have some significant conflicts with A.C. Part of the annual celebration involves A.C. and his sons hiking up the mountain to camp out overnight.  One son is staying behind at the lodge, ostensibly with an injured ankle. Conan is invited to join the camp out, and it is only A.C.'s snoring which wakes Conan and sends him wandering out of camp to look at the stars, minutes before a landslide buries the campsite and--presumably--A.C. and two of his sons.  Conan races down the mountain as a freak blizzard moves in and barely survives hypothermia in getting back to the lodge to deliver the sad news. Conan is sure he heard a separate explosion moments before the landslide started and he thinks this is an elaborately plotted murder, not an accident of nature. That means somebody at the lodge is involved, and Conan means to find out who. Everyone has a motive--most of them centered around money. If you enjoy reading books set in the Pacific Northwest and like a decently wrought mystery, this would be an enjoyable choice.
