Thank you, said Holmes. The envelope too, please. Postmark, London, S.W. Date, July 7. Hum. Mans thumb mark on corner, probably postman. Best quality paper. Envelopes at sixpence a packet. Particular man in his stationery. No address. Be at the third pillar from the left outside the Lyceum Theatre to night at seven oclock. If you are distrustful, bring two friends. You are a wronged woman, and shall have justice. Do not bring police.
