Dear Harry,

I think I see a chance of establishing your innocence beyond any possible doubt. Please follow my instructions minutely. Go to Agrasato’s curio shop. Ask to see something “out of the ordinary,” “for a special occasion.” The man will then ask you to “come into the back room.” Go with him. You will find a messenger who will bring you to me. Do exactly as he tells you. Be sure and bring the diamonds with you. Not a word to anyone.

Dear Harry,
