The Protector by SJ Deas is a sequel to The Royalist, which I read several years ago and enjoyed. This second book continues the story of William Falkland, a former Royalist soldier who has reluctantly found himself in the service of Oliver Cromwell. It’s 1646, the First Civil War is over (the Second will begin within two years), and Henry Warbeck, Cromwell’s man, has again approached Falkland to ask for his assistance with another investigation. Anne Agar, sister of John Milton, the epic poet and writer of political pamphlets, has disappeared and Cromwell believes she has been abducted by Royalists in an attempt to convert the pro-Parliamentarian Milton to their cause.

Falkland is less than enthusiastic about taking on this mission; after four years of war he no longer feels any strong allegiance to either side and just wants to go home to his wife and children. However, that’s easier said than done, as he returns to find his house abandoned and his family missing, with no idea where they have gone or why they have left. Hoping that Cromwell will help him to locate his own family in return for tracking down Anne, Falkland sets out on her trail – but the biggest obstacle in his way turns out to be Milton himself, who takes an instant dislike to Falkland and is unwilling to cooperate.

As well as being an interesting and compelling mystery novel, The Protector is also quite a sad and poignant portrayal of the human cost of war, with families left divided, destroyed and separated once the fighting ends. William Falkland is a sympathetic and tragic hero as, lost and lonely, he begins the hunt for Anne Agar while despairing of ever finding his own beloved Caro. I was pleased to see him team up again with Kate Cain (whom we first met in The Royalist), but at the same time I was glad that Deas doesn’t push them into a romance, leaving us in no doubt that William is still devoted to Caro and the children and will continue his search unless and until there is no hope left.
