Coincidentally, this bore some resemblance to "Silent in the Grave (Lady Julia Grey #1)" by Deanna Raybourn - a young and headstrong widow in Victorian times discovers some threatening notes in her late husband's books and papers and realizes he wasn't the man she thought he was. Since I read them almost back to back, I can't help but compare them. Alexander's novel is certainly slower paced and earns the tagline of "a novel of suspense" but I found it a touch more realistic. Emily doesn't go pursuing an investigation, teaming up with a P.I., and barreling headlong into dangerous situations like Julia did, in fact she largely ignores the clues that drop in her lap until she can't deny them any longer. While amateur sleuthing novels are fun, they can come across as somewhat fabricated sometimes and this one didn't feel that way.
Although slow paced, I really enjoyed watching Emily discover herself through her discovery of her late husband. With a few amusing stumbles and a touch of pretension, Emily evolved from a naive blank slate to a fully formed independent woman - and, oh yeah, uncovered and righted a crime too.
