Young Sherlock Holmes knows that adults have their secrets. But he could not even imagine that one of the world's most famous assassins, officially declared dead, was actually alive and hiding in Surrey and that his brother Mycroft was somehow involved in this. When no one tells you the truth, you have to take the risk to find out for yourself. Thus begins an adventure that will lead Sherlock to America - to the very center of a deadly web, where life is not worth a penny, and the truth has a price that no reasonable person would agree to pay.
