Before we went to Montreal...

Just before Our first session of Horror's Heart, I've decided to have another scenario. For two reasons. First is, of course, reminding of Pulp Cthulhu rules after a long time not playing in this particular iteration of  BRP system. The second reason is to give my wife's character a special amulet. I want to give her some Deep One jewelry with 30 points of Luck. It may seem a bit too much, but remember she will be playing all alone in a campaign.
My first choice was Isle of Madness by Ed Possing from Miskatonic Repository. This is my first product from that line. It is quick, nasty little adventure. Cannot wait to run it. Maybe even this week!
Here it is in my possession:
