The Devlin Diary by Christi Phillips

This novel actually tells two stories - one set in the modern day and the other set during the reign of Charles II of England.

Hannah Devlin, a female doctor in 1672, is called to court to treat one of the mistresses of Charles II. Reluctantly, she gets involved in court intrigue and the mysterious murders of two courtiers. Could their deaths be related to the death of her own father a year previous? And is the murderer the intriguing Ralph Montagu or another doctor, Edward Strathern?

In the modern day, newly minted PhD Claire Donovan is teaching at Cambridge University. She and another Cambridge professor (both characters were introduced in The Rossetti Letter) become caught up in their research of the Devlin diary - and its relationship to the death of yet another Cambridge professor.

The author tells both stories in alternating chapters. Sometimes I wanted to skip ahead and find out what was going to happen! I learned a lot about Cambridge and also about the reign of Charles II, both subjects of interest to me. A quick read and very entertaining.
