Lost copy of 'The Catcher in the Rye' last seen near a café close to the Edinburgh Book Festival venue.

I've misplaced my copy of 'The Catcher in the Rye' while visiting the Edinburgh Book Festival last weekend. I last remember having it while sitting at a café near the venue. The book has my name written on the inside cover, and it means a lot to me as it's a gift from my late grandmother.
