Cliffhangers can be kind of like mysteries. When any program on the 2023 TV schedule ends an episode or a season with a point that needs to be resolved, you’d surely hope for it to be wrapped up at some point in the future. Sadly, for fans of the series "Mystery 101," that sort of resolution currently looks to be lost, thanks to Hallmark cancelling it without one last hurrah to tie off the loose ends left by 2021’s series finale.

In September 2021, "Mystery 101: Deadly History" aired on Hallmark Movies & Mysteries, and it left one hell of a cliffhanger in its wake. After seven adventures of the sort of “will they, or won’t they?” banter you’d expect from characters like Professor Amy Winslow (Jill Wagner) and Detective Travis Burke (Kristoffer Polaha), the couple actually looked to be headed down the path of “they will.” That is, it looked that way until the final scene involved a time jump that kicked off a new case: Travis investigating the death of Amy’s fiancé.
