It's Felix's birthday tomorrow! His best friend, Fiona, has promised to bake cupcakes to celebrate, and Felix can't wait. But the next morning, Fiona arrives at the party with no cupcakes... and a tall tale that's as colorful as raspberry icing with lemon sprinkles. Fiona's little lie points the finger at three likely suspects, but Felix has a feeling that she might be getting in deeper and deeper. Now Fiona doesn't know which is worse--forgetfulness or a queasy conscience. Luckily she has a friend like Felix to whisper some advice into her ear!
