Ahmed

Ahmed is a minor antagonist in Stan Frederick. His sister contacted Stan clients as Ahmed had "been acting weird". It turned out that he was being haunted by the Rake. Ahmed murdered his sister as the Rake told him to, whispering her name to him. He later used the Rake as an excuse to try to murder Stan, that the Rake had whispered Stan to him as well. But that could not have been true because Stan isn't his real name, it's an alias. Meaning that Ahmed simply wanted to kill.
