Dr Bob Nicholson explores police archives and rarely seen documents to uncover the story of the second assassin - 19-year-old John Francis, who gave up a successful career as a carpenter in the West End of London to become a tobacconist. The business soon failed and after his landlord caught him stealing money, Francis bought a pistol and on the 29th May 1842, he fired at the Queen outside Buckingham Palace. Prince Albert spotted him from their carriage, but none of the guards saw Francis, and so he escaped. When informed of the attempt, the Prime Minister Robert Peel urged Victoria to remain in the palace until the mysterious assassin had been caught, but she had no intention of agreeing to the plan. The Queen wanted to ride out as usual the following day - and would let herself be the bait. Bob Nicholson finds out what happens next, and to determine a motive, delves into John Francis’ past.
