You know the adventure is good when players ask if they can play it again as you're cleaning up.
I ran it with a large group of friends and family. It fit my group really well meeting the interests of friends who regularly play D&D and friends who love murder mystery games but hadn't played D&D before.
I loved how each of the roles were well fleshed out. Even though we barely dived into all the details the players really liked having interconnecting backstories. No one in my group wanted to play the spouse role, so I quickly made up an assistant to the conductor borrowing bits of the spouse background. The module is really flexable that swapping out a character still works the same, and doesn't put too much work on the DM.
