Deadlock

I received a copy of Deadlock by DiAnn Mills from NetGalley in exchange for an honest review.
Two murders have rocked the city of Houston. Are they the work of a serial killer, or is a copycat trying to get away with murder?

That is the question facing Special Agent Bethany Sanchez, who is eager for her new assignment in violent crimes but anxious about meeting her new partner. Special Agent Thatcher Graves once arrested her brother, and he has a reputation for being a maverick. Plus, their investigative styles couldn’t be more opposite: he operates on instinct, while she goes by the book.

When hot leads soon fizzle out, their differences threaten to leave them deadlocked. But an attempt on their lives turns up the heat and brings them closer together, and a third victim might yield the clue that will help them zero in on a killer. This could be the case of their careers . . . if they can survive long enough to solve it.

Another great book by DiAnn Mills.  She does a great job of making her characters relatable and so real.  I had a very hard time putting down the book.  This was another case where I didn't see most of the twists coming and couldn't guess who Scorpion was until the very last.
