An Assignment For Croup And Vandemar

Richard's been captured by Serpentine, & he doesn't know why, Mr Croup and Mr Vandemar are back, and to top it off the Marquis thinks he and Door should enlist them to rescue Richard. Are the killers loyal, or are there deeper plots afoot? Much Croup and Vandemar - wonderful fun to write "I prefer not to think of it as murder, but as an art form." Mr Croup.
