I've recently started a sort of mini-campaign of CoC for my players that takes place in the present. Right now they are about 1/3 in and I wanted to break things up by starting the next session with a (hopefully) short vignette.
What I am thinking of doing is having them wake up as a person who is already being held prisoner by the "cult" they are headed to. The prisoner wakes with little or no recollection of who they are or how they got there (hence no need for back story), but attempts to sneak out of his cell (which someone has left a way out of), and ultimately can meet up with the PCs later, or simply be recaptured, and...
What I am wondering is this, how shall I split up the character between my players? Should I simply do a time share (you have five minutes, then pass to the next player), or is there a more creative solution I am not thinking of?
Has anyone done something like this before? Any input is appreciated!
