What happened to Diana and Dodi in the Alma Tunnel on the night of August 31, 1997? Was Diana six weeks pregnant? Was she about to get engaged and married to Dodi? Had Dodi purchased an engagement ring for her? Was he planning to present it to her that night? Was Andanson an SIS operative, trained to use his white Fiat Uno to tip the Mercedes car, causing it to career into the 13th pillar in the tunnel? Why was he found, deep in a forest, beheaded in his burnt out, keyless, locked car, with a bullet wound in his head? Is Tomlinson, ex-SIS agent, absolutely right when he says the Mercedes "car accident" was a classically planned SIS method of execution, one he knew was being planned to assassinate a former Serbian leader? What was the bright light witnesses saw in the tunnel that night? Was it a strobe light used to blind the driver? What was the loud bang they heard before the crash? Did Diana tell a medic that she wished to be buried with Dodi as she lay dying? Was Diana a half-sister to Jemima Khan?
