First in a British mystery series featuring Imogen Quy, the college nurse for St. Agatha's college at Cambridge. This was a new-to-me author, and despite finding the main character a bit stodgy and the writing style a bit formal and stuffy, I actually devoured this book in one evening. Well-plotted, wonderful descriptions, and over the course of the book I did warm up to the main character eventually.
When one of the students is found dead inside the locked Wyndham Library at the college, speculation begins as to whether he was murdered or it was an accident. Aside from his head injury, which appears to have happened in a fall, there was no initial evidence of foul play. But how did he get into the library in the first place? The students are being decidedly uncooperative with the police, and Imogen's friend, DS Mike Parsons, asks her to see if she can influence them to be more forthcoming with information. I actually did figure the mystery out fairly early, but I wasn't sure enough of my deduction and wanted to read to the end to find out. Definitely want to read more in this series.
Admirerers of Agatha Christie or Ngaio Marsh will find the writing style of Jill Paton Walsh's initial offering of the Imogen Quy series quite similar. A few twists and turns in the puzzle of how and why a quiet student is found dead in one of the college libraries will keep you turning the pages non-stop.
(Side note: Jill Paton Walsh was chosen by the Estate of Dorothy L. Sayers to complete Sayer's last Lord Peter Wimsey novel)
