Istanbul: Letters and Seals

You, the merchants of Istanbul, have come up with a new and quite lucrative way of earning extra money: delivering messages to the shopkeepers of the bazaar! While doing so, you can catch some useful information here and there that you can sell to the secret society for rubies. In order to keep your regular business running, you have hired a companion who is actively supporting you. True, he is a little slower than you would like but in return he does not require any assistants.
