Detective,

Thank you for reading my letter at such short notice. My prize key has gone missing and I am sure some young whelk has stolen it. You must get it back!

I have found a variety of clues but, alas, I am too old to follow them with any success. The first clue lies with the Blue Bird and my loyal subordinate, Henri. Follow the trail, recover my missing key, and you will be hansomely rewarded...

Good luck.

The Mayor
