Anatomy of an Alibi by Ashley Elston
If you're looking for a good twisty mystery during this never-ending winter, check out Anatomy of an Alibi. It starts with one woman (Aubrey) impersonating another (Camille) so the latter can investigate what her husband (Ben) is up to and why he wanted his wife out of town. Unfortunately for Ashley, Camille, and Ben's law partner, Hank, they all become suspects when Ben is found murdered. It's a gripping story of wealth, power, suspicion, and greed. Couldn't put it down.
