Wideawake was one of the most difficult prisoners that Dartmoor, and later Duxford Convict Establishment, could remember. He was not violent - with one memorable exception, when after serving the full twelve years of his sentence for jewel robbery and assault he had walked straight out of prison and, on the very first evening of his release, waylaid and stabbed a warder who (he said) had victimised him. This foolhardy gesture got him an immediate further sentence of eight years' imprisonment. The fact was that Wideawake was uncanny. He was an educated man, who had been a solicitor's clerk; he had 'advanced' political views, which he was not afraid of expressing; and he scarcely ever slept (hence his prison name). And since Wideawake - or Frank Stayman, to give him his real name - was the only man who knew where the loot of his greatest robbery - seven priceless, matching diamonds - lay hidden, it was clear that when he did finally emerge from prison some very unexpected wheels were likely to start turning.
