Ouija Board bounced back to winning form with an impressive success in the Princess Royal John Doyle Stakes at Newmarket.
Ed Dunlop's filly, winner of the English and Irish Oaks last year, had disappointed on her only start this season, although it later transpired she had suffered a stress fracture.
But the four-year-old showed she was well over that problem as she strolled to success under Frankie Dettori in the Group Three contest.
Dettori settled his mount at the back of the field before pulling her to the outside with half a mile of the 12-furlong contest to run.
Ouija Board was travelling ominously well and quickly overhauled leader Mango Mischief to accelerate clear.
Although Briolette threw down a late challenge, Dettori only had to give the 11-8 favourite a couple of cracks with the whip before easing down on the line for a two-and-a-half-length win.
Dettori was delighted with her performance and celebrated with a flying dismount in the winner's enclosure.
He told BBC Sport: "She felt awesome going to post and it's really full credit to Ed. She has had problems but the filly is really special."
"He can look to any target now. She gave me a fantastic feel, especially for a horse that has missed most of the season."
"I was very taken, I must say."
Dunlop added: "I'm very pleased for her and for her owner (Lord Derby). She's had a lot of problems, but she's won really well."
"Frankie went a little earlier than he probably wanted to. She's pricked her ears and kept on racing and that's her style."
"Frankie said she's a machine and he said the only filly he's ridden like her was Balanchine (winner of the Oaks and Irish Derby in 1994)."
Ouija Board is entered in next week's Prix de l'Arc de Triomphe at Longchamp as well as the Prix de l'Opera on the same card, while a defence of her Breeders' Cup Filly & Mare Turf title is also in the offing.
"She's in the Opera and the Arc and there's America as well, but we won't make any rash decisions until we have got her home and I have spoken to the owner, " said Dunlop.
"We will see how she is, but all options are open to her."
