In 'The Cases of Mystery Lane,' an Attorney and Her Sleuthing Husband Get Mixed Up in a Murder

A married couple find themselves entangled in a murder investigation.

While Hallmark is known for their predictable rom-coms, viewers still enjoy them and love to see a happy ending. It's a formula that works, but Hallmark has been trying to shake things up a bit. Last year's Three Wise Men and a Baby was more about the relationship between three brothers with the romance story serving as the B storyline.

In the upcoming The Cases of Mystery Lane, the couple in the Hallmark Movies & Mysteries film are already married and things aren't necessarily sailing smoothly. Here's everything we know about the movie including a Parade.com sneak peek.
