Dear Officer Ashfield,
I would like to most humbly request access to documents concerning the new experimental "chokedust" which you may have recently found yourself in possession of. I understand this is a delicate subject matter, and I assure you every precaution will be taken with the documents to ensure they remain confidential. If access to these documents is agreeable to you, please have one of your men deliver them to my cell.
Respectfully,Your friend in A25
