John Gosden’s Elusive Kate completed a four-timer with a wide-margin victory in the Total Prix Marcel Boussac at Longchamp.
Although trained in Newmarket, the 4-1 shot was scoring in France for the third successive time following two victories at Deauville.
William Buick was happy to go to the front from the outset and she led her rivals into the straight, quickening the tempo all the time.
Hot favourite Zantenda looked a big danger soon after the turn for home but was taken right over to the far rail by Olivier Peslier and could never land a blow.
Elusive Kate was hanging over to the other side of the track in the closing stages, but it was not enough to stop her scoring decisively from Irish raider Fire Lily, with Zantenda only third.
Gosden's wife Rachel Hood part-owns the horse and said: ``She's a beautiful filly and I'm only sorry that our partners from America couldn't be here.
“It was unusual to see her drift, but she’s only a baby and was trying to do her best.”
Gosden himself said: “She’s a pretty good filly. She ran right-handed at Deauville but she got confused in the downhill section (here), the ground is a little quicker there.
“She changed her legs and ended up in the middle of the track. You shouldn’t win from there and I thought the favourite should have won.
“She likes coming to France, so we’ll come back here for the Guineas (Poule d’Essai des Pouliches) and she may go to Churchill for the Breeders’ Cup.”
Buick said: ``I was a bit worried before the race as she was a bit buzzy and she isn't normally.
“If there was no pace in the race my plan was always going to be to go to the front, but I thought she might be a bit buzzy to do that.
“She broke well and pricked her ears, but she hung left from halfway and I didn’t really understand why she was doing it.
“When I asked her to quicken in the straight she was really decisive and I didn’t know where the others were.
“It seems like she’s won very easy and ultimately it was a very good performance.
“She was running downhill for the first time, it was probably greenness but it’s not really an issue because she won very easily.”
Fire Lily's trainer David Wachman said: ``The winner has won well, but she (Fire Lily) has been second in two Group Ones now and is an exciting proposition for next year. She has been here so might come back for the Pouliches.''
