The problems begin when Rory and Longinus are summoned to the Assassins' Guild.

Longinus wants Rory to change into something more elegant - not going to happen.

Rory can't make Longinus stop calling her his assistant.

Their problems get worse when the Guildmaster asks them both to investigate an attack against her and find out who is behind it. If they fail, the consequences will be....unpleasant. And it looks like the attempted assassination is mixed up in dangerous Guild politics.

Between their arguments and making sure the assassins they're investigating don't kill them, it's one hell of a challenge.
