Moriarty's Last Riddle

Sherlocks!

Moriarty seems to be dead, but before his death he organized one last scheme on a grand scale.

Only the real Sherlocks have the ability to follow the almost invisible track that the evil genius left behind and reveal the terror that he planned. A duel of two minds, two sides, they are like yin and yang, so similar yet so different.

Will you Sherlocks be able to solve it?

The clock is ticking!
