Tintin Hardcover - The Calculus Affair

A sensational invention by Professor Calculus begins by wreaking havoc at Marlinspike Hall: every window shatters, along with most glass objects! Unfortunately, this brainchild won’t be heading to the pranks-and-gags aisle. Spies are trying to capture Calculus to extract his plans. It turns out the kidnappers are Bordurians, eternal enemies of the Syldavians, determined to turn Calculus’s invention into a weapon of mass destruction. Hardcover
