A Marquis & A Bloody Mystery by K. Sterling

Victorian London isn’t ready for Reginald.

Reginald and Paul are in the UK, hiding while things cool down after the heist at the FBI Headquarters. Burnt out and frazzled from chasing after Speed, Reginald uses a potent combination of drugs to shut down his brain so he can rest but his plan backfires in the most unusual way. He wakes up in Victorian England as one of his ancestors and has to solve a string of yuletide murders as a marquis.
Luckily, he has help from a very familiar cast of characters. Join Reginald as he crashes into the past to solve a mystery with very serious modern implications for our Lake Cliff heroes.
