CNN has released a haunting trailer for what may be the final episode of Anthony Bourdain‘s Parts Unknown, two weeks after the celebrity chef and author took his own life in France.

The upcoming episode, which will be the conclusion of the eleventh season, sees Bourdain travelling to Bhutan, along with Black Swan director Darren Aronofsky.

Overnight, French authorities revealed the results of toxicology tests conducted on the chef, with prosecutor Christian de Rocquigny telling Reuters that his system contained:

“… no trace of narcotics, no trace of any toxic products, no trace of medicines, no trace of alcohol.”

61-year-old Anthony Bourdain spoke openly about his use of drugs like heroin and cocaine as a young chef in the 1980s. Though he had quit narcotics by 1990, he continued to enjoy drinking throughout his life, and in his first memoir, he wrote:

“Most people who kick heroin and cocaine have to give up on everything. Maybe because my experiences were so awful in the end, I’ve never been tempted to relapse. You see me drink myself stupid on my show all the time. And I have a lot of fun doing that. But I’m not sitting at home having a cocktail. Never, ever. I don’t ever drink in my house. … When I indulge, I indulge. But I don’t let it bleed over into the rest of my life.”

Bordain was in France filming an episode of Parts Unknown at the time of his death, although it remains unclear whether CNN will attempt to release a twelfth season of the show.
