From Tardis Wiki, the free Doctor Who reference

The Child Princess of Padrivole Regency 9 was the young ruler of the 9th Regency of the Padrivole domain. She was a Padrivole herself and had rosey cheeks, golden curls, and a fluttery voice.

The Child Princess was murdered by a Plasmavore called Florence Finnegan who was jealous of the Princess' appearance. Her death was avenged by the Judoon, who were sent out to find Florence. Florence hid out in the Royal Hope Hospital on Earth which was outside of Judoon jurisdiction, but the Judoon pulled the hospital to the Moon, neutral territory where they hunted the killer. With the help of the Tenth Doctor and Martha Jones, the Judoon located the Princess' killer who boastfully confessed to the murder, stating that the Princess had it coming. The Judoon executed Florence on the spot for her crime of murdering the Princess. (TV: Smith and Jones)
