Help with a horse please

Not a jumps fan, but I saw a successful pointer run and win about 4 weeks ago. It might well have been its racecourse debut and it duly obliged winning by about 10 lengths of odds around 20/1. It was probably a Saturday as it was televised and it won on a left- handed track. Heading for Cheltenham and it's odds were cut by all bookies after the race. Can anybody help with the name of the horse please?
