Dear Boss,
I keep on hearing the police have caught me but they wont fix me just yet. I have laughed when they look so clever and talk about being on the right track. I am down on intelligence and I shan't quit dripping them till I do get jailed. Grand work the last job was. I gave the officers no time to stop me. How can they catch me now? I love my work and want to start again. You will soon hear of me with my funny little games. ha. ha. Keep this letter back till I do a bit more work, then give it out straight. I want to get to work right away if I get a chance. Good Luck.
Yours truly,
Jack the Dripper
