Very little to no explanation about the nature of the scion/demi-god in the condensed rules or characters descriptions. No clue about how the murder was commit, no possibility to inspect the victim body, no clue how the "suspects" are related or why (very poor reasons in some case) they have been choosen as suspect. Usually you should get that information up front. I've run a lot of investigations adventures (Cthulhu/Vampire) and this one was pretty bad. I suppose you should own the rulebook before playing this adventure. No longer any interest in buying it after reading this Jumpstart.
