Book Obsession

So, since Stuart McLean passed away earlier this month, I've been on the hunt for his books. I now have most of the series...

I'm missing #5. Although, I don't know what #5 is called. And neither does anyone else. Most of the books are a reprint from earlier editions, but just printed in Penguin Publishing's series of #1 to #11. And no one (not even faithful and usually reliable Google, the girl at Chapters/Indigo, or the staff at Black Bond Books) can tell me what the #5 book is called and if it's even in print or not. Suffice to say, I may have to contact Penguin Publishing to figure out this little mystery. In the meantime, I have lots of Vinyl Café stories to keep me busy!
