It is an old maxim of mine that when you have excluded the impossible, whatever remains, however improbable, must be the truth.

Sherlock Holmes, "The the sign of the Four"

My name is Bradley Peak and today I will try my hand as a detective of the 21st century.

I shall try to crack a case that has been stirring in the minds of internet-goers for over 10 years.
