Didn’t know SH was so amazing,
A second degree mind palace,
He was keeping.
What we watched in an hour,
And were perplexed by, for days,
Had taken place in his mind,
In mere 300 seconds!

Baffled with the news of return of Moriarty,
He decides to solve a similar case,
That had occurred 120 years ago.
He recreates his whole life,
Complete,
With *Irene’s photograph,
In his pocket watch.
Fits all the pieces in 1895,
All,
Including John’s witty wife,

Then enters the ‘cleverer one’,
And fatter this time,
Having already made a theory,
He asks Sherlock to do the leg-work,
Because Mycroft himself is busy,
Trying to beat his little brother.
The game is afoot again,
All in Sherlock’s complex brain,
He exposes the truth,
Of Mrs. Ricoletti’s death,
Just as he was about to know about Moriarty’s,
He’s is woken by his friend.

But he goes back again,
To complete the story.
To solve the mystery,
He goes to the Falls,
To again finish the problem,
The final problem.
But this time John interrupts,
In 1895,
And kicks Moriarty off the cliff,
To let Mr. Holmes happily, alone,
Complete the fall.
Now he returns to the present,
With a smile conveying I-know-it-all,
And he does know all about the villain,
His death, his plans,
*And the rest.
