Elementary my dear Watson~.

First the man, that being you, told me upon the night of the 10th that you had favorited all three of my most recent cards. This means that you, being the only one who had done so that I didn't recollect meeting before, was the culprit.

The second clue was the age on your account. According to your profile you are 20. Well knowing the fact that very few people actually bother to change there ages on DA once they have an account, being too busy uploading art and the like, I new you were in the ballpark.

Putting both of these together, I knew that you were the only person who could have done this! *makes dramatic pointing pose*

*turns to Scotland-yard Policeman*

He's all yours.

*policeman starts to try to arrest, but is stopped*

Oh heavens no don't do that. He hasn't commited a crime at all. Give him cake.

*hands Josh cake*
