When a mysterious rival uses a time machine to frame Detective William Murdoch of a murder he didn’t commit, his great-great-great granddaughter Macy and her friends, Zane and Billie, must travel back to 1910 to re-examine the clues and find the real perpetrator of the crime. But if you thought solving a regular murder mystery was difficult, imagine doing so undercover, in a time that isn’t your own, and without the help of modern technology. To make matters worse, if Macy doesn’t succeed in exonerating Murdoch, she faces a terrible fate — being erased from the future!
