The father is Mehmas, a sprinting sire whose offspring tend to be quick, sharp horses that hit the ground running early in their careers — useful traits for a two-year-old still finding its feet. The mother's side brings influence from Kitten's Joy, an American sire associated with horses that are a touch more versatile and often improve with time and distance. Whether Thieve takes after the speed on the father's side or the stamina on the mother's remains to be seen.
What is not in doubt is the quality of the stable behind this horse. Roger Varian's Newmarket yard has sent out 86 winners already this season — that is the kind of output that puts you firmly among the best operations in British racing. Varian has a strong reputation for introducing younger horses patiently and getting the best out of them over time, which means even a quiet debut would not be cause for alarm. When this team decide a horse is ready to run, it is usually worth paying attention.
