The 2017 entry in P. J. Tracy's "Monkeewrench" series. P. J. Tracy was a mother-daughter writing team, but mom passed away. The daughter continues the series here without a glitch.
As always, there are two crime-fighting teams here: there's the Minneapolis Police Department detectives, concentrating on the able and likeable duo of Magozzi and Rolseth. And then there's "Monkeewrench", an elite team of super-hackers. An important link: Magozzi is sweet on chief-Monkewrencher Grace. To the extent that (in this book) she's pregant with his child.
But as far as crime goes: there's a serial killer on the loose in the Twin Cities, gruesomely preying upon young women jogging in parks after dark. Which understandably is occupying the cops.
But the Monkeewrench folks are taking their show on the road, responding to a southwest Minnesota farmer whose daughter has gone missing. Are these two investigations linked. (Spoiler: yah, you betcha.)
There's also a lion that provides an important clue. (Yes, I said: a lion. Honest.) And a very bad storm which leads to more gruesomeness.
The series is not my favorite, but it's pretty good.
