Sir David Frost, who balanced a life of hard-hitting political interviews with satire and Through the Keyhole, is set to have his own life investigated.

Frost died in August last year at the age of 74, and now his career will be documented with Frost on Frost, a new book from Ebury Publishing’s WH Allen.

But where does one start for the man who turned down a training contract with Nottingham Forest FC and was once so in demand on both sides of the Atlantic that he was, for a time, Concorde’s most frequent flyer?

The book will be, according to the publishers, an “epic story of personal achievement set amid a rapidly changing world, encountering the great and the good who have dominated news and entertainment over the last 50 years”.

Writer Neil Hegarty will write it with the help of the broadcaster’s widow, Lady Carina Fitzalan-Howard, and their three sons. The family have promised to leave no stone unturned, providing access to Frost’s archives and to a menagerie of his former subjects. Frost interviewed all eight British Prime Ministers from 1964 and seven US Presidents — including, of course, Richard Nixon — to the point that he was more recognisable than the UK power set to American politicians. On one occasion, George W Bush visited Downing Street and was surrounded by high-profile Brits when Frost walked in. “Now at last here’s someone I recognise,” Bush exclaimed.

“Dad always sought to discover what made people tick,” Frost’s son Wilfred says, “and I look forward to helping Neil do exactly the same with Dad.” One wonders if he is ready for the racier side of his father’s early career. “The Sixties was a perfect time, in many ways, in terms of your private life,” Frost once told an interviewer.

“I had a marvellous time. And, hopefully, so did they.”
