"That was the kind of chance that must be taken when one holes up in known and regularly checked haunts. The risk was not enormous, in fact it was small – but it was still there. And when tried, sentenced and waiting for death it is no consolation to know that what came off was a hundred to one chance. To keep going and to maintain the one-man battle the enemy had to be outwitted, if possible, all along the line and all the time."
