So that’s lunch-time and most of the afternoon ruined then. Earlier, just as I started unwrapping my sandwiches, Autocar’s editor-in-chief Steve Cropley – knowing my fondness for motor racing – deposited a Formula 1 themed book onto my desk.

The book is entitled ‘Ayrton Senna: All His Races’ and written by long-time Formula 1 scribe Tony Dodgins, with a foreword by Martin Brundle, Senna’s great rival in Formula Three. 

As the title of the book suggests, it charts every race the Brazilian contested, from his formative exploits in karting through to that fateful Formula 1 race at Imola in 1994. 

This means that although I’m supposed to be writing a review of the Vauxhall Cascada I drove at the weekend, I’m instead reminiscing about Senna’s victory in the 1987 Monaco Grand Prix for Lotus.
