Answer by taking a quote from the following article:

Cook was born at his parents' house, "Shearbridge", in Middle Warberry Road, Torquay, Devon. He was the only son and eldest of the three children of Alexander Edward "Alec" Cook (1906-1984), a colonial civil servant, and his wife Ethel Catherine Margaret, nee Mayo (1908-1994). He was educated at Radley College and Pembroke College, Cambridge, where he studied French and German. As a student, Cook initially intended to become a career diplomat like his father, but Britain "had run out of colonies", as he put it.

In late 1989, Cook married for the third time, to Malaysian-born property developer Chiew Lin Chong (1945-2016) in Torbay, Devon. She provided him with some stability in his personal life and he reduced his drinking, to the extent that for a time he was teetotal. He lived alone in a small 18th-century house in Perrins Walk, Hampstead, while his wife kept her own property only 100 yards away.  Cook returned to the BBC as Sir Arthur Streeb-Greebling for an appearance with Ludovic Kennedy in A Life in Pieces. The 12 interviews saw Sir Arthur recount his life based on the Twelve Days of Christmas. Unscripted interviews with Cook as Streeb-Greebling and satirist Chris Morris were recorded in late 1993 and broadcast as Why Bother? on BBC Radio 3. Morris described them:  It was a very different style of improvisation from what I'd been used to, working with people like Steve Coogan, Doon Mackichan and Rebecca Front, because those On the Hour and The Day Today things were about trying to establish a character within a situation, and Peter Cook was really doing 'knight's move' and 'double knight's move' thinking to construct jokes or ridiculous scenes flipping back on themselves, and it was amazing. I mean, I held out no great hopes that he wouldn't be a boozy old sack of lard with his hair falling out and scarcely able to get a sentence out, because he hadn't given much evidence that that wouldn't be the case. But, in fact, he stumbled in with a Safeways bag full of Kestrel lager and loads of fags and then proceeded to skip about mentally with the agility of a grasshopper. Really quite extraordinary.  On 17 December 1993, Cook appeared on Clive Anderson Talks Back as four characters - biscuit tester and alien abductee Norman House, football manager and motivational speaker Alan Latchley, judge Sir James Beauchamp and rock legend Eric Daley. The following day he appeared on BBC2 performing links for Arena's "Radio Night". He also appeared, on 26 December, in the 1993 Christmas special of One Foot in the Grave ("One Foot in the Algarve"), playing a muckraking tabloid photographer. Before the end of the next year his mother died, and a grief-stricken Cook returned to heavy drinking. He made his last TV appearance on the show Pebble Mill at One in November 1994.

was this successful?
