Owner Jeff Smith and trainer David Elsworth were able to enjoy the latest high in what has been a long-running partnership when Arabian Queen (4/1) lowered the colours of Andre Fabre's odds-on French raider High Celebrity.
The pair's greatest moments together came through the popular stayer Persian Punch, but another of the stars in the purple and blue silks was Barshiba, Arabian Queen's dam.
Such is the esteem in which Fabre is held in this country, High Celebrity went off at 4/9 after a facile victory in a Chantilly maiden.
Queen Mary sixth Arabian Queen was sent straight to the lead by Moore on her first attempt at six furlongs and he gradually wound up the gallop with the help of the rail, never letting Maxime Guyon get too close and booting her past the line a length and a quarter in front.
"It's probably a bit of 'Fabre-itis'," said Elsworth. "Andre's very clued up, and he gets respected.
"But I believe mine is a good filly, and the second horse would have looked a good winner if we weren't there.
"Barshiba stayed well, but this filly has speed. I think she'll stay a mile, and I believe there's a Group One in Newmarket next spring."
Smith said: "We could look at the Lowther at York next, and her main aim will be the Cheveley Park."
Fabre said: "She had only had one run so there was the lack of experience. At one point I thought she was going to win easily but Maxime said the ground didn't help her.
"In all I'm a bit disappointed, but on the other hand I'm happy. She'll probably go to Deauville next."
