Back at Norstedts, Mörk also received an email from Varotto. “Sorry Catherine,” the message read. “Could you please give me the Hushmail code?” Altrov Berg dashed off a separate message to Varotto, asking if everything was okay.

Suddenly, her phone rang. “Why are you sending me this?” Varotto asked. Altrov Berg explained what was happening. Varotto was confused. She hadn’t sent any emails to Norstedts all day.
