Special delivery To: Jo Shrewsbury From: Iain Forbes
Even though it's not her birthday (technically, it's his), Iain has sent Jo a cake in the shape of two Bludgers, with two Beater's bats crossed underneath them. The words Happy 34th Birthday, Fred! are written in gold and red frosting above the Quidditch equipment. No note is included, but Jo will know it's from Iain because it's been enchanted to explode the second someone tries to cut into the Bludger on the right.
A few minutes later, another owl will deliver a regular cake, one that will not explode. This one is for eating purposes, obviously. No need to waste two perfectly good cakes...
