I was only one year old when the deadliest bombing in British history shocked the world.

In December 1988, Pan Am Flight 103 was detonated—an incident that killed all 259 people on board, as well as 11 people on the ground in the Scottish town of Lockerbie.

When Abd al-Baset al-Megrahi, a Libyan intelligence officer, was convicted in 2001 for the bombing, I was a teenager. When he later died, I thought the story had largely come to an end.

But it wasn’t.

The case is still ongoing and, toward the end of this year, Abu Agila Masoud—the man suspected of building an explosive device that destroyed an aircraft—is set to be tried in Washington, D.C.

I found the chance to look at this complex case with fresh eyes and a deeper perspective. The more I investigated, the more complicated the Lockerbie case became—so much so that at times I didn’t know what to believe.
