The game is a 1920s murder mystery, so... I don't want to spoil things. But I did have a very good time, and it's a very solid game that is complicated enough to be interesting, but simple enough to be pretty easy to run and play. (So if you have an ambition to run a larp, here's one you can download and get cracking. That's what these things are for.)
The player mix was good, and I only knew a couple of them well, and a few more somewhat more vaguely. So at least half the people are now people that I'll know only by their character names...
I don't have any criticisms, but I'll mention one detail, just because my mind would not let it go. The setting is left vague, but the reference to Prohibition places it in America, but the character names all read to me as quite English (Harringdon, Stirling, Fairfax, Smyth-Montague...) more so than even the WASPiest of enclaves on the east coast (at least I imagine so -- I'm not invited to those parties). This is somewhat reinforced by the inspiration that the larp lifts from Dame Agatha.
OK, two more details from the run:
I wore great-great-grandfather's watch.
Rattled Suspect: It makes no sense to accuse me. I had the opportunity to kill him numerous times on other nights.
Me: So how many times did you kill him tonight?
