Looking toward the station, he sees more Bletchley girls, WAAFs and WRENs, coming towards him; the day shift, finished with their work, which consists of the processing of ostensibly random letters and digits on a heavy-industrial scale. Not wanting to appear ridiculous in their sight, he finally gets Duffel maneuvered onto his back, gets his arms through the shoulder straps, and allows its weight to throw him forward across the bridge.
