Chickok Hens considers himself the greatest detective of Cockland Yard, much to the dislike of his rival, inspector Lestrowl. However, it's actually Hens' sidekick, Dr. Wrenson, who always saves the Peckerstreet duo from certain cock-a-doodle-doom. Be it their nemesis, Professor Doviaty, throwing a stone to kill them both, or the charming-but-deadly Irene Eagler setting the featherbrained detective's heart aflutter.
If you think these puns are bad, I should probably mention that English isn't my native language, and that Hens originally was called "Huhnes". They are still bad, but, uh, that's how it's supposed to be. Kinda.
