You all know Roger Moore, 007? If you are too young to know what he looks like, he looks like me,’ said our small, squat, spectacularly un-debonair Thai tour guide, Captain Alex, with a deadpan face.

While not exactly shaken with laughter at his wry quips, everyone was stirred by the stunning scenery at Ko Khao Phing Kan, or James Bond Island, as this place is more famously known.

It became a must-see site due to its double-O heaven setting in The Man With The Golden Gun, when Moore’s Bond goes in search of Scaramanga, played with relish by Christopher Lee.

This was all heady stuff for a first-time visitor to Thailand, an exotic land that has also inspired on the big screen the sublime (The Beach) and the ridiculous (The Hangover, Part II).

Many writers, from Somerset Maugham to Graham Greene, have fallen for Thailand’s bars, silk, curry and hospitality. Its ancient history, temples, islands and beaches, as well as the gentle people of unrivalled grace, have made it endlessly enchanting.

A small bit of detective work led me to deduce that John le Carré found his original inspiration for The Night Manager – his recently televised thriller – in Thailand after staying at The Mandarin Oriental hotel in Bangkok, on the banks of the Chao Phraya river.

I discovered his fascination for the legendary hotelier Kurt Wachtveitl, famed for decades for arranging anything and everything with charm and discretion, just as we saw Tom Hiddleston’s character do in the BBC series.

More later about le Carré, a drunken night on champagne, and his eternal gratitude to the night manager.

But first back to James Bond Island. This speck in Phang Nga Bay is firmly on the tourist track as boatloads arrive to get their fix of the legendary spy.

Indeed, everyone else on our boat seemed to think they were wannabe secret agents, as the men stripped down to Daniel Craig-style swimming shorts and the women wore Bond-girl bikinis.

They also donned their best Bond-villain shades for selfies in front of the limestone outcrops. But then Thailand plays to everyone’s beach fantasy.

Captain Alex’s tour included kayaking into sea caves, shopping for silk, and then a lunch of fresh grilled fish, before driving back to the Banyan Tree Hotel in Phuket, where smiling courtesy is second nature to its staff. It is a tranquil base after a day spent in little towns with noisy bars and shops.

Phuket became a favourite destination of backpackers in the 1960s and 1970s thanks to its sleepy beauty and sensational beaches, and the luxury hotel chains soon discovered its appeal too.

Many of the villas in the Banyan have a private pool, and there’s a complimentary spa treatment every day in your garden overlooking the lagoon. Bicycles make it easy to get to and from the main lobby and its zen-like spa.

The starting point for my trip before heading to Phuket was Bangkok and the splendid Mandarin Oriental Hotel, which for decades has been the grand meeting point of kings and queens, rock stars and writers, who have made it their essential stopover.

It is oddly relaxed and ungrand, but leave so much as half an apple in your room and it will be replaced within the hour.

Some simple sleuthing persuaded Frank that le Carré first came across his inspiration for The Night Manager in Bangkok's Mandarin Oriental hotel. Pictured here are cast members Tom Hollander, Olivia Colman, Elizabeth Debicki, Tom Hiddleston and Hugh Laurie

As well as supreme service, there is nothing the staff haven’t seen, from Billy Idol smashing up his suite to Somerset Maugham fighting off a bout of malaria.

Some simple sleuthing persuaded me that le Carré first came across his inspiration for The Night Manager here. The clues were staring me in the face in the le Carré suite on the tenth floor.

A typed letter from the author is framed on the wall. He thanks the hotel manager for the incredible care and hospitality, having arrived ‘tired, dusty and unannounced’ after a ‘swing through divided Laos’ while researching his novel, The Honourable Schoolboy.

He recounts how he met up with a friend in the hotel and drank copious amounts of champagne, which annoyed a journalist from ‘a lofty London paper’ who was also staying there.

‘I fear we may not have seemed as funny to him as we did to one another.

A year later, when The Honourable Schoolboy finally appeared, the same correspondent took time off from his political musing to give it a perfectly dreadful review.

How sobering to reflect the Mandarin Oriental can dispense correction to the overbearing as well as champagne to the thirsty.’

The fact that le Carré bothered to send such a letter to the manager indicates his fascination at how Wachtveitl looked after him and the dozens of others guests, all seemingly effortlessly.

Incidentally, the room opposite le Carré’s is the Barbara Cartland suite, for those who are more inclined to soft romance than spy thriller.

Just outside the hotel, Bangkok shows all its buzz and brashness, with street food, shopping (incredible silver), mai tai cocktails at sunset at bars both grand and grubby.

There has always a sense of being about to enter the land of all possibilities, be it The Beach, Bridge On The River Kwai, or Bond.

Just remember not to turn it into The Hangover…
