Abaddon's Puppet

Publisher's blurb: In February 1587, Elizabeth I had Mary Queen of Scots executed, an event that eventually led to the attempted Spanish invasion of Britain in 1588. Before that, however, King Philip of Spain plotted to have Elizabeth overthrown in favour of her Catholic cousin. This is one of those plots. Abaddon's Puppet is an investigation for 2-4 Agents during which they will uncover a deadly occult threat to the crown.
