4 down for the Sherlock Holmes Canon Reread.
Oh and this one! :D Because I'm about to start writing the sequel. So it's research.
That last one is still in progress.
On the list for next month
A couple of new ones, eagerly awaited! And book number 5 for the Sherlock Holmes reread - The Hound of the Baskervilles. I have an audiobook of that too, so it might end up read twice in June. A couple of non-fiction titles mixing things up a bit.
