Four-hour TV series being made with Germany’s Tandem Communications.

Scott Free UK has secured the option to adapt Kate Mosse’s bestselling novel Labyrinth as a four-hour TV series with Germany’s Tandem Communications.

It will be the first time the UK branch of Scott Free has partnered with Tandem and taken responsibility for an adaptation.

The two companies have previously worked together on versions of Ken Follett’s historical novel Pillars Of The Earth and its sequel World Without End, but it was Scott Free LA that took the lead.

Pillars of the Earth was picked up by Channel 4, among others, while World Without End has been greenlit by Germany’s ProSieben-Sat.1, Spain’s Cuatro, Austria’s ORF and Sky Italia.

ProSiebenSat.1 is also close to co-financing Labyrinth, which it is thought will cost $15m (£9.3m) to make.

An international bestseller that has been published in more than 38 languages, the novel will be adapted by writer Adrian Hodges. Kate Mosse will work as a consultant and Scott Free’s UK head Liza Marshall, who negotiated the option on the book, will also be involved.

Once the deal is finalised, Sat.1 will broadcast the series, but a UK broadcaster is yet to pick it up.

The book follows two heroines based in the present and 13th century during the Cathar massacres, as they race to save a 4,000-year-old secret.

Filming will take place in the south of France and is due to start in September.
