Episode 3 of the Digital Playground British-made series has Danny D's inspector character interrogating his country's queen Valentina Nappi about the murder, and her flashback recollection of the night's activities is filled with sex, but zero clues.
Accompanied by her bodyguard Alex Donald, she witnesses guest Honour May having sex on a pool table with Sam Bourne, and gets turned on. After she briefly sees her hostess Ella Hughes having a spat outdoors with the victim (which we've already seen before), Xander Corvus seduces her and treats her to the thrill of one of Ella's sex toys, a vibrator.
All this achieves is giving her an alibi, namely that she was humping Xander when the murder occurred. All we get in terms of the mystery is that Danny makes a mysterious phone call afterward, making his actions seem more suspect than those of the suspects he's interviewing. The antique phone he uses makes this (along with the costuming) seem like a period piece, but the sex toy vibrator is up to date.
