Never Send Flowers is the thirteenth James Bond continuation novel by British Writer John Gardner. I have the hardback copy sans jacket (although might design my own over time) first published in 1993 by Hodder & Stoughton. Below I’ve noted the London locations mentioned. Don’t forget to check out the physical London Bond Map to aid your trip to the big smoke and happy hunting.

Ch1 – Week of the Assassins 

“The Honourable Archie Shaw MP, was one of the country’s favourite politicians, […] lunched at “Le Chat Noir”, his favourite restaurant in Chelsea.” Pg3 & Pg4. 9 Beaumont Avenue, W14 9LP

Ch2 – Gazing Down at Jungfrau

“Bond is summoned to by Moneypenny to the suite of offices occupied by M and his personal staff, on the ninth floor of the anonymous building overlooking Regent’s Park.” Pg11. 

Ch6 – Smoke and Mirrors

Bond attempts to shake off his surveillance by,
“Hailing a passing taxi he told the driver to take him to Austin Reed’s in Regent Street. […] Austin Reed’s store occupies almost an entire block on the west side of Regents Street, a few blocks from Piccadilly Circus.” Pg67.

In 1911 The first Austin Reed flagship at 103-113 Regent Street. in 2011 Austin Reed moves from the original 103-113 Regent Street Store to the opposite side (100 Regent Street). As this book was first published in 1993, Gardner will be referring to the original store. Austin Reed went into administration in 2016 with 120 stores closing. Read more here.

Gardener describes Bond’s house as a,
“Regency house which stands on a quiet tree-lined street off the King’s Road. […] The street off King’s Road where Bond lived was a cul-de-sac, the preferred kind of location for anyone in his profession. “You either live out in the open, with a lot of ground between you and the rest of the world, or you choose a street with only one entrance or exit,” one of the instructors had told him years ago. “Preferably, a short street.” the old expert had added.” Pg68-69.
This literary house has been mentioned a few times, more notably in John Pearson’s The Authorised Biography of 007, (all locations here) and is generally considered to be 30 Wellington Square.
Bond receives a letter warning him of the surveillance and is told to meet his contact at Brown’s Hotel,
“We have met once but I shall not give you my name in writing. I shall take tea at Brown’s Hotel each afternoon this week between four and six.” Pg70. 33 Albemarle St, W1S 4BP.
Further mention of the hotel and rendezvous commences on Pg73 after Bond manages to shake his surveillance by setting fire to his house. Probably my favourite bit in the book. According to WIKI Brown’s is London’s oldest luxury hotel having never been renamed, rebuilt or relocated.

Ch8 – This Is How It Must End

“On the previous night, Bond had found himself expected at the Inn on the Park.” (Pg86. Hamilton Place, Park Lane, W1J 7DR).
It was built in 1970 as the Inn on the Park London. After investments and renovations it was reopened as Four Seasons Hotel London at Park Lane as a luxury 5-star hotel in London.

Ch11 – The Trail of Blood

Bond questions Dragonpol about his movements at the time of the murders,
“I got into Heathrow, let me see around six in the evening. Had dinner with a dealer and arranged for him to bid for me – certain items of interest were coming up for sale at Sotheby’s.” Pg123.  
Bond visited Sotheby’s in Octopussy which I featured in a previous post.

Ch12 – The Time Machine 

Bond is on the run with Flicka and takes refuge in the Old Globe Theatre where a production of Midsummer Night’s Dream,
“There were cobblestones underfoot, and others pressing in towards the high curving wooden walls of the old Globe Theatre.” Pg132.
As this book was first published in 1993, Gardner will be referring to the original theatre. A modern reconstruction of the Globe, named “Shakespeare’s Globe”, opened in 1997 approximately 750 feet from the site of the original. Address: 125 Park St, SE1 9EW.
