Did Philo write the Gospel of Mark?

I never really did expect to come over a suggestion like this, but in an article, posted on the web this is exactly what is argued: in "Mark the Cryptic Gospel:The Origin of Christianity, the author (Audrey Fletcher) tries to argue that Philo was the man behind the Gospel of Mark! "The key to the cryptic Gospel of "Mark" is the author. To whom then among the influential Jews of Alexandria in the first century AD could be attributed the composition of "Mark", and what was his purpose? The only possible candidate is Philo of Alexandria."
I am not sure if the author is serious! You may read the article for yourself; I will comment on it when the weekend is over!
