Recommendation for a game for teenagers

I'm looking for a murder mystery game for teenagers, and I'd like it to be completely appropriate- i.e. no references to infidelity or other mature content. It also needs to be for 35 people (I'm ok making up a few extras if needed).

Do you have any recommendations for that?

My response:

I suggest you have a look at Mysteries-on-the-Net or Murder-Mystery-USA.

They both have games suitable for teenagers for the numbers you suggest. (But I don't know the details myself, so you'll have to make your own judgement.)
