With America at war, Tom Swift reluctantly agrees to design a war tank for the government, while neighbours whisper that he is a slacker. Spies and queer doings surround his works as he and his friend Ned build the great caterpillar machine, and Tank A’s trial journey across Tinkle Creek becomes a test of courage as well as engineering.
A wartime instalment of the famous inventor series, for collectors and fans of vintage technological adventure. Download the free EPUB.
