I was a bit disapointed by this one I must say and it took me a bothersome long time to read this one because:
yes the characters are attractive to read,
but the whole crime-solving plot was … maybe better than a lot of others, but what is a detective story in which the detectives achieve nearly nothing, until the murderer reveils himself to them? The only valuable connection was Poe and Baltimore. But why not screen through the files and check everybody like they said, instead of dragging the plot along until it is time for the final dramatic scene?
And SPOILER come on, it was clear very very soon, who the murder was!
So, although the two main characters were a hot couple this story is only a 3-stars-read.
