Mr. Churchill's secretary a novel

In the beginning, Maggie is in London after completing her PhD in mathematics in America but can't find a suitable job coz all of them are for Oxbridge educated upper class men. When she gets offered job as Churchill's secretary, she accepts it albeit a little reluctantly, because she wants to be a part of the war effort. At the same time, she is also trying to find the details about their parents' death. She is surrounded by great friends, who all band together when the air raids begin. There is also espionage, surveillance and code breaking here.

I loved Maggie's character. She is educated, brilliant, confident, brave and a great friend. I loved her friends, especially David who is so loyal and supportive. The mystery here is quite thin, I could guess the assassin about halfway through the book and all conflicts get resolved within a couple of pages. But this book is still fun to read. It is fast paced, has some witty dialogue and on the whole, is quite entertaining. I am going to continue with the series to read more of Maggie's adventures.
