The summons came as Johanson was preparing to drive out to the lake. On his return from Kiel he’d contacted Tina Lund to tell her about the experiment in the deep-sea simulation chamber. They hadn’t talked for long: Lund was up to her ears in work, and spent every spare second with Kare Sverdrup. Johanson had had the impression that her mind was elsewhere, but whatever was bothering her didn’t seem to relate to her job, so he didn’t ask questions.
