Here we go again.

Another puzzle to solve.

Another cruel death.

As I took a look around the location, I saw Sherlock's eyes flitting between different points of interest to him. I sighed and returned my gaze to the victim, trying to decipher what I was certain Sherlock had figured out already. Out of the corner of my eye I saw him turn and stroll off, a brisk spring in his step.

I could almost hear his brain whirring, his ideas spinning around at the speed of light inside his incredible mind.

We solved the case within days. I admit, it was mostly Sherlock, but every genius has his flaws. He may give the impression that he knows everything… of course he is constantly outshining me, proving me wrong. It's a given.

He's always three steps ahead.

But occasionally, just once in a while, he strays down the wrong path, he takes complex, winding routes which are just impossible. No-one can figure out these paths, including Sherlock himself.

And that's why I'm here. To point out those obvious little clues he misses, to show him why his brilliant theory is not all that brilliant.

I know I'm not the brightest, the sharpest, the best. But I'm still here. After all, every good genius needs someone to prove them wrong now and again.

It keeps him on his toes.
