Lee and Drew have been like brothers ever since adolescence. So when Drew betrays Lee in the heat of a tumultuous night in Glasgow, the two men find themselves entangled in a bitter grudge that went way beyond what they could imagine, as the violence and bitterness of the wrestling ring, spilled over into the real world. Grudges are typically seen as dangerous, negative emotions. But is there a glimmer of light to be found amid the darkness of resentment? Matthew Syed questions both the hidden values and harsh consequences of grudges.
