The Curse Of The Diogenes Club

London 1899. The Prince Regent’s New Year’s Eve ball is in full swing when several explosions shatter the festivity. Were they an attempt to assassinate the heir to the throne or, as it seems, intended for Mycroft Holmes himself? What is even less clear is the casus belli - is it related to the powerful Diogenes Club, or perhaps to the untimely death of the Russian Ambassador's estranged wife.
