The basic premise is that the PCs inherit a warehouse, and gain an invitation to a notorious gambling event. While some of the party are playing games of chance, others may be attempting rescues, burglary, or gaining information. I would recommend using multiple hooks from the given list, and would definitely include the rescue of a nobleman's daughter as the PCs are given a vital sketch map. Success will be measured in monetary profit, not numbers of foes slain.
Remarkable similarity to tackling a (Sean Connery/Roger Moore era) Bond villain: (i) you play him at games of chance; (ii) he has an exotic partner; (iii) owns a grand residence; (iv) his henchmen wear brightly coloured clothes; (v) one possible task is "rescue the girl"; (vi) crocodiles and big cats to avoid; (vii) opponents killed in horrific/unusual ways (acid bath).
Strengths: (i) Plenty for the PCs to do, and ample motivation to do it. They need gambling funds, so will wish to fence paintings from the warehouse; exploring the sewers will pave the way for a stealthy entry into the mansion. (ii) Interesting distinctive magic items. (A hallmark of this author.) (iii) Many intriguing NPCs well described in just a few words; should be a roleplaying treat. (iv) Lots of potential follow up encounters. (v) Nice clear maps gathered at the end.
Cautions/Weaknesses: (i) Referees will need to read the whole carefully and manage a divided party; it might benefit from a paragraph describing a likely chain of events. (ii) Does it really take one hour to play Shut the Box with nine players? A few minutes seems more reasonable. (iii) Kellerin should have extra cash in the games room, so that he can buy out gambling pledges. (iv) Some tables have very small print.
This version appears identical to a free download from the author's website. Whatever happens, it should be exciting. In play, my group were big monetary winners; they rescued the nobleman's daughter, robbed some chests, but one character was slain by a surprise attacker. As a PWYW offering, happy to give this full marks. Highly recommended.
