A low concrete room of an underground cipher-bureau bunker, bare concrete walls and a vaulted ceiling, a single caged electric bulb hanging from the ceiling, two wooden crates standing open on the concrete floor, an Enigma replica packed in wood wool inside one of them, papers and wiring diagrams stacked in the other, a plain wooden table with a second machine under a cloth, a steel door standing ajar onto a dark corridor.
Jeder Verweis nennt seine Art. „Vorläufer“ allein wäre eine Behauptung.
