Immortal Verse is a bay filly with no white markings bred by her owner Richard C Strauss's County Limerick-based Kilfrush Stud.

[2] Her dam Side of Paradise won the listed Prix La Camargo at Saint-Cloud Racecourse in 2001,[3] and was a half-sister to Last Tycoon and the Goldene Peitsche winner Astronef.

On her first appearance as a three-year-old, Immortal Verse started joint-favourite for the Prix du Louvre over 1600 metres at Longchamp but finished fourth of the seven runners after being hampered in the closing stages.

[6] Two weeks later at Longchamp, Immortal Verse started a 25/1 outsider for the Poule d'Essai des Pouliches: she never looked likely to win and finished eleventh of the sixteen runners behind Golden Lilac.

The field included Esperita and Mixed Intention, who had finished ahead of Immortal Verse in the Pouliches and the Chartwell Fillies' Stakes winner Perfect Tribute from England.

Immortal Verse accelerated past all her opponents, took the lead a furlong out, and drew away to win by two and a quarter lengths from Nova Hawk with Barefoot Lady taking third place.

The other runners included Sahpresa, Dick Turpin (Prix Jean Prat), Cityscape (Joel Stakes), Worthadd (Derby Italiano) and Tin Horse (Poule d'Essai des Poulains).

According to Collet she was working in Chantilly forest when a jogger disturbed two deer which ran across the path, causing Immortal Verse to panic, break loose and sustain a minor leg injury.

[12] In October, Immortal Verse was sent to Britain for a third time for the Queen Elizabeth II Stakes at Ascot in which she was matched against the outstanding colt Frankel.

[14][15] Her 2019 foal by Caravaggio, named Tenebrism, won the 2021 Cheveley Park Stakes to give Immortal Verse a first Group One win as a broodmare.
