In 1936 twelve-year-old streeter Lewis Carter finds himself in Berlin, Germany, at the heart of Nazi territory, on a convoluted trail to uncovering the whereabouts of his long-missing, presumed-dead father, Professor Harold Carter. Lewis is armed with a street map, an address...and of course his best friend, Pearl Alice Clavell. But even Pearl' s wealthy and somewhat suspect connections cannot protect them from the dangers that lurk at every swastika-draped corner. As they draw closer to finding Lewis' s father, they discover that the professor is at the center of a deadly plot that threatens global stability and the very outcome of the impending war. The two friends must use all their street wiles— with the help of a Flash or two— to save the day, as well as their skins!
