When a woman is killed after stealing a memory, a washed up detective tracks her killer, who begins to taunt him with more victims and memories.

The mechanics of your story world are hard to grasp from this logline -- perhaps it's worth leaning more heavily on the human and easy to grasp aspect of the story. (Detective must catch a killer).

That being the case:

- it's not clear how the initial murder is connected personally to the detective in question. It just feels like the character's job ... and even if that's the case, it's not like there is anything at stake if the protagonist fails in his goal beside faceless victims. (For instance, could the protagonist be about to be kicked off the force, and he needs to do this job well in order to keep his job?) Or -- was the victim somehow linked to the protagonist?

- it's not clear WHY the antagonist is taunting this particular cop. What beef does he have with him? Why taunt him?

>>>the death of his wife and daughter

Spielberg has been there, done that with the protagonist? in "The Minority Report".? What's the point of having those ghosts in his memory bank, anyway?? To provide a pseudo-psycho explanation for his addiction to other people's memories?? If so, IMHO, it's a shallow, mucho overused and abused gimmick.?

To repeat; I think you have a great story hook.? Please dig deeper. (My 2.5 cents worth.)
