The Vampire Ship: The seizure of Europe's largest heroin shipment
Really realty good read. I expect a novel in the future and a Netflix adaptation.Some notes:
1) "As the Noor One was approaching the island on its way to Elefsina, he said, a smaller vessel had swung past it, picked up a ton of its heroin, then went up the Adriatic toward ports near Serbia." - What ports would that be? (answer: Serbia doesn't have ports in Adriatic)2) “I only remember him because he was really fat otherwise if he would be a normal man he probably wouldn’t get my attention,” he said. “I repeat, he was REALLY FAT." 
I laughed out loud on this one :D3) Deaths that are not mentioned here are those of product users. I mean seizure affect price which affect what heroin gets cut with. Users get use to diluted batch and then when a fresh shipment hits the market it catches them off guard with it's potency which leads to overdose. This is at least what I was told as the reason of death of some people I knew died from it.4) A significant amount of cocaine has been seized recently. By significant I mean 1 ton! 
Guys are Croatian, none of them had priors.https://www.occrp.org/en/daily/13112-spanish-police-seize-cr...As in OP's story, deaths of those involved will surely follow.
