The standalone novel “Strangers at the Gate” is set in a fictional sunless valley in Scotland in the middle of winter.

McPherson’s long-running Dandy Gilver series continues with “A Step So Grave,” the thirteenth entry in the series. Set at windswept Wester Ross just before the wedding of Dandy’s son, the bride’s mother is murdered in a tale twisted with Gaelic folklore and superstitions.
