Harry is called to a piece of wasteland where the body of a Hasidic man has been found, as the medical crime drama continues. Noach Maraowski, a Rabbi from the Hasidic community, confirms that it’s his nephew, Yitshok.

Wanting to treat the closed, deeply sensitive community with care and respect, Leo suggests that they respect their wishes and perform a “dry” post mortem – using scans and an external examination rather than opening up the body. Harry reluctantly agrees. The post mortem reveals boot marks covering Yitshok’s body; he was clearly the victim of a vicious attack.

Esther, the dead man’s wife, says that Yitshok went missing on Saturday evening. Harry finds a forensic link to a group of Polish labourers, one of whom, Aleksi, has footage on his phone of them attacking Yitshok – but the investigation stalls when they discover that the attack happened the night before Yitshok went missing. Harry performs a full post mortem, against the wishes of the community, and discovers that Esther is lying about the time of Yitshok’s disappearance. However, she refuses to admit that he went missing on Friday evening rather than Saturday, even though this could help to convict Aleksi.

Harry discovers why when he finds a faded manuscript hidden in Yitshok’s belongings. A young Hasidim, Chaim, explains that it is the story of Jonathan and David – a passage of the Torah treasured by gay Hasidic men as it seems to condone homosexuality. Confronted by the evidence, Esther admits that she knew about Yitshok’s sexuality. On Friday, when they were supposed to have Shabbat supper with Noach, Yitshok claimed to be ill, but had gone out, apparently looking for sex instead. Deeply ashamed and terrified of his sexuality being exposed, Esther lied about the time of his disappearance.
