Criminal Minds. Fox Meridian, #4

When Marie lands what seems to be the chance of a lifetime, starring in a new, rather low-budget, action movie based on the Whitechapel murders, she is thrilled. But when sex workers begin being murdered, their bodies mutilated in a chillingly familiar fashion it falls to Fox Meridian to hunt down the killer. But it seems that the new Jack has a few tricks up his sleeve which the old one did not. He lives no evidence behind and seems able to get into places no human should be able to.
And he seems to be looking for Marie Jane Kelly, the last woman the real Jack murdered, and the character played by Marie in the film.
