What may matter more is who is saddling up the horse. Trainer J P Murtagh, based at Coolaghknock Glebe in County Kildare, has already sent out 53 winners this season—a productive outfit that clearly knows how to prepare a runner for the track. A yard that busy and successful doesn't usually waste time on a horse it doesn't fancy, which is a quiet vote of confidence in Pas De Deux before a single race is run. Beyond that, there is nothing to go on. The debut will tell you almost everything: whether the horse likes the experience, whether it has the speed to trouble the better runners, and whether it belongs in company at all. Some debut runners look hopelessly out of place. Others suggest they have been waiting all summer to get to this moment. Right now Pas De Deux is a complete mystery—and that is exactly as it should be.
