In 1483 two young princes vanished without a trace in the Tower of London. The prime suspect in their disappearance has long been their uncle, Richard III. But despite centuries of fierce debate, Richard’s guilt has proven impossible to pin down for certain.

We re-examine the historical evidence and speak to experts Lauren Johnson, Nathen Amin, Matt Lewis, Chris Skidmore and Leanda De Lisle, for their take on what really happened in one of history’s most fascinating cold cases.
