Madeline is a model at the studio of Paris-based fashion designer François Lemaire, and also acts as his assistant.
She appears in the episode Alias Mr. Hackenbacker.
Sky Anxiety: High-Fashion, and Hijacked!Edit
Madeline, Deirdre and François drive to the airport together to meet Skythrust, the venue for his latest fashion show. The jetliner takes off, bound for London; and the show begins - with Deirdre, Madeline and Lady Penelope modelling various couture from Lemaire's newest collection. And the show is a great success...
But then, Madeline and her cohort, Mason, hijack Skythrust - and hold Deirdre, Penelope, Lemaire and the rest of the passengers and crew at gunpoint, as hostages. Skythrust's pilot, Captain Ashton, is then instructed to fly the plane to a certain obscure location in the Sahara Desert, where the rest of the gang is waiting to abscond with Lemaire's entire collection, made of a revolutionary (and potentially lucrative) new fabric called Penelon.
Unknown to anyone aboard Skythrust, however, an International Rescue agent is in their midst...
...and, responding to Penelope's covert emergency signal, Thunderbirds 1 and 2 are quickly dispatched to intercept the hijacked Skythrust before it can reach the Sahara rendezvous point...
After Thunderbird 2 knocks out the jetliner's undercarriage with a missile, Ashton tells Mason that they have no alternative but to head for London International Airport, where they at least have the facilities to handle a crash-landing. Reluctantly, he agrees. At Ashton's behest, Madeline and Mason retreat to the back of the plane for safety...
The incoming aircraft prepares to crash-land at London Airport, but then the secret 'Hackenbacker Device' comes into play - a rear-mounted, ejectible fuel-pod, which flies free and can then be safely detonated.
After the plane safely touches down, Lady Penelope holds the hijackers at gunpoint until the police arrive.
- Madeline's puppet later went on to portray Professor Marshall in Ricochet, and the Indian Fortune-Teller in Thunderbird 6. It also appeared briefly as a guest at Harman's Christmas Party in Give or Take a Million, and at The Swinging Star in Thunderbirds Are Go (film). In Lord Parker's 'Oliday it played a hotel guest.
