The Thirty-Nine Stripes

S1 E6: Sections of four different paintings are mysteriously being stolen. After being duped several times, Dan discovers the "thief" is a small robot being controlled by the soda machine vendor. The sections, put together, reveal the major circuit of an enemy power's new master computer. Putting the plans in paintings was the only thing the undercover pole position agent could get the information out of the enemy country.
