Fallen Splendour by Jackson Marsh

“We have his sisters. Involve your catamite, and they will die before the shortest day.”

A kidnapping, a threat and a deadly showdown force Lord Clearwater and his coachman, Andrej, on a secret mission to save two innocent girls. But where are they? The clue to the location is wrapped up in a Tennyson poem, and time is fast running out.
Left at Clearwater House to crack the code, James finds himself with another ominous responsibility when Inspector Adelaide makes an arrest. With his master missing, it falls to the footman to crack the code, fight a court case, and save Archer’s reputation.
With only three days to find the answers, all evidence points to a location known only to Tennyson himself, and an enemy thought dead.
But what if James is wrong?
