1. The Bomb

Myles Bonnar pieces together the original police investigation.

He goes back to the night of the explosion; tracking down three sources, each with unique insight into how the police investigation unfolded.

From the very early days it’s clear confusion and conspiracy are taking hold.

Rumours circulate. Why are American special agents on board the flight? Was the plane used to smuggle drugs? Who are those mysterious figures in the woods in Lockerbie?

The police investigation narrows in on a Palestinian militant group. But are they the real culprits?
