Under a Killing Moon
 

sounds to me like under a killing moon, it was an fps adventure game by access software with fmv scenes.

Is it the Blackwell Chronicles
 

In that game there was a Sam spade dude or gal who solved mysteries but I think it is protected and not abandonware. But if this is not it at least I put my own suggestion in to help you.:)

I could of swore those access games were traditional point and click 3rd person perspective games. Been a while so I suppose I could be wrong =)

I know that the hover car stuff was in 1st person though. That was in under a killing moon right, or is that one of their others?

Mean Streets is the one I was thinking about...where you drive the hover car.

I think it may be one of the later Tex Murphy games. Under a Killing Moon? Pandora Directive had a club scene.

11th hour?
