This book is full of awkwardly-inserted mentions of real places in Harvard Square, Cambridge, and downtown Boston and environs. It almost feels sometimes like the story is a vehicle for describing the locale and showing off local knowledge. A lot of it is accurate (I work in Harvard Square, and did live in Cambridge at the time this book was written.) I did laugh at the mention of the "Fresh Pond Bread and Circus" - I'm pretty sure that's been a Whole Foods since before 2003(?). There are also lots of awkwardly-inserted descriptions of food and recipes. Aside from that, the writing is OK and engaging enough.
I actually like that this was not a traditional murder mystery - in fact there is not a murder to "solve" in this book.
However, both the main character and the woman in the diary she finds behave in ways I do not find plausible or even justifiable. In many cases, they have better options, but their actions are presented as the only possible thing to do.
The main character does seem a bit snobby, especially about food and cooking. There seemed to be some unintentional irony because she is such a snob about other people's cooking but she also volunteers in a soup kitchen where needy people have to eat food of no particular quality.
I have to admit, I don't completely understand the conclusion of the book. (How did the professor know that Faith Fairchild had found the diary? He seemed to know about the diary, but not to have read it or know what it's about.) Ultimately I don't think these kinds of details matter, and most mystery books' solutions fall apart if you think about them too much, so I'm not deducting any points for that.
Quick read, could have been a lot worse. ***
