Nah nahnah nah nah you can't catch me !

read the facebook message from Moriarty,

Sherlock reached for his calabash and the needle

shouted for Mrs Hudson

went into a dream.

 

Watson was stuck without a computer,

so a boy was sent to fetch him at once

but the doctor was checking Mrs Watson

and didn't give a fig for his friend,

 

 

When Sherlock saw the light again

his options were as plain as a hansom's whip

he unfriended the blackguard then and there

 

and that's how poems like this can end.
