Revenger is the second in the John Shakespeare historical series by Rory Clements. Per
SYKM, it was the winner of the 2010 Historical Dagger Award. It has dropped to $0.99 at Kindle US.

Also, if you prefer to read in order, the first in the series,
Martyr, is only $1.99, a very reasonable price for a backlist title, IMO, although it has been down to $0.99 in the past.
