Who Killed Cock Robin?

Not the sparrow, for a start. Having researched the matter I find the name on his firearms licence to be Sparron, clearly somebody else entirely. The only witness was the fly, but could he, with his compound eye, have recognised sparrow at that distance? I doubt it. Then we come to the fish who claims to have caught his blood. Fish was convicted the previous year for riding a bicycle with no lights so his testimony can be ignored. The beetle might indeed have made the shroud but the shroud was the wrong size entirely for Cock Robin and appears to have been made for a creature with three legs and no head, with a head-shaped leg where its head should have been. The more I researched, the more suspicious the death looked and I began to wonder whether Mr. Robin was indeed dead at all. Where, for example, is the body? Buried, claims the owl. Just what I'd do if I had a secret. Do honest owls bury bodies? I think not. Remember Kennedy? Remember Roswell? Well then.

We need to have an immediate inquiry with me as Important Person and everybody calling me Sir. Only that way will the truth come out. I should have a uniform too. And a special hat.
