Murder On The Mount

Description for MURDER ON THE MOUNT by Sandy Dengler:

Jack and his ever-faithful Labrador Retriever, Maxx, spend a cold Christmas on Mount Rainier, trying to find out who killed an enthusiastic environmental activist. With suspects ranging from a druid who believes Mount Rainier is sacred ground to another activist who's campaigning for wheelchair access to the top of the 14,000-foot peak, it should be an interesting case.

This is #3 in A Jack Prester Mystery.
