Jack (Daniel Lissing) and Bill (Jack Wagner) find the evidence they need to arrest Gowen (Martin Cummins), before discovering clues that point to another suspect, in this week's new episode of When Calls the Heart, airing Sunday, March 27 at 9 p.m. ET/PT on Hallmark.

Meanwhile, Abigail (Lori Loughlin) is reeling from the unexpected arrival of Becky and Cody's (Carter Ryan Evancic) aunt, who has already made plans to take the children home with her.

Elsewhere, Elizabeth (Erin Krakow) encourages Becky not to give up on science despite her aunt's new plans for the girl's future, and Rosemary (Pascale Hutton) is presented with the opportunity of her dreams in Hollywood, before being cast in the true role of a lifetime.
