Secret agent women and a suitcase full of intrigue? Count me in

Chapters 1 through 3 really pulled me in. Chapter 1's Grace is doing her morning walk of shame when she's diverted from her preferred course. Instead, she must traverse Grand Central Station, in which she finds a suitcase full of photos. Chapter 2's Eleanor and Chapter 3's Marie are secret agents in the 40's. Not much is given away in the First Look, but I am sure the photos all tie in with Eleanor and Marie. I want this book. I don't like the cover. It just didn't do anything for me, and I thought the big clock was of a church's stained glass window at first glance.
