Who knew getting J.K. Rowling to come to your book club was a piece of cake?

After what may be the sweetest Twitter chat that ever was, the Orkney Library in Scotland successfully enticed the famous author to its facility for a book club meeting. The bait? Cake with lemon drizzle, Irish Examiner reports.

It all began when the library tweeted out an announcement for its Saturday Slaughters book club last weekend, when the group would be discussing The Cuckoo's Calling by Robert Galbraith -- the pseudonym under which Rowling writes the Cormoran Strike novels.

Join us for Saturday Slaughters today at 2.30pm. We shall be discussing The Cuckoo's Calling by @RGalbraith pic.twitter.com/ux6ar9gcnW — Orkney Library (@OrkneyLibrary) March 5, 2016

Rowling, being an avid Twitter user, saw the tweet and commented:

That’s when the library made a ballsy move, urging Rowling to attend. The good-humored author didn't miss a beat and joked that she'd use a magical form of teleportation to get there.

After one more joke about Rowling’s means of transportation, the library baked up a brilliant bribe:

@jk_rowling @RGalbraith We would be delighted with either of you. Perhaps we should add that there will be cake. — Orkney Library (@OrkneyLibrary) March 4, 2016

And just like anyone with a sugar tooth, Rowling acted accordingly:

@OrkneyLibrary @RGalbraith Robert (and Strike) are both partial to fruitcake. Something with a bit of heft to it. I like lemon drizzle cake. — J.K. Rowling (@jk_rowling) March 4, 2016

The library, of course, stood by its offer:

And we have the lemon cake on standby just in case @jk_rowling turns up #shopbought #weapologise pic.twitter.com/AmADuuEE42 — Orkney Library (@OrkneyLibrary) March 5, 2016

Naturally no one thought Rowling would actually show up, but she did -- there’s even photographic evidence:

We had a very special guest at Saturday Slaughters today. Thanks so much @jk_rowling Come back soon x pic.twitter.com/GVaXSVX88O — Orkney Library (@OrkneyLibrary) March 5, 2016

According to The Guardian, the library’s Twitter feed, run by librarian Stewart Bain -- who happens to be Publishers’ Publicity Circles librarian of the year -- is famous for its sharp sense of humor. Some of Bain's gems include his commentary on someone's decision to circle every Wally (or Waldo) in this book:

Where's Wally trending reminds us of the book returned with Wally circled on every page. We had to amend the title pic.twitter.com/OaGLlF5avd — Orkney Library (@OrkneyLibrary) March 5, 2015

And his appreciation for this winner from the library’s archives:

Rowling is such a fan of the feed, that she even went out of her way to pose with that book during her visit:

.@OrkneyLibrary I had the best time! Thanks for wonderful chat, cake and, of course, letting me touch The Book. pic.twitter.com/VCrU2lJAT6 — J.K. Rowling (@jk_rowling) March 5, 2016

All in all, although the library didn’t use a by-the-book method to get Rowling to its facility, you have to applaud this truly novel approach.
