As previously noted, I'm listening to these in altogether the wrong order. This is another short story, #6.5 in the St. Mary's series.
It's Christmas, and time for certain traditions to be observed. One of those traditions is, of course, Max's illegal jump to solve a problem that coulld become something much, much worse. She, Markham, and Peterson head off to ancient Egypt to retrieve a handgun accidentally left behind by an agent who should never have brought it in the first place.
But this is St. Mary's, and another unbreakable tradition is that things will go horribly, improbably, in ways that only very smart people trying to avoid trouble could manage.
The characters remain interesting, exasperating, and fun to spend time with, and continue to appeal to my slightly twisted sense of humor.
