The New Men by C.P. Snow

The same evening that Hanna visited me, Martin was talking to Captain Smith. Sawbridge was called by telephone some hours later, and ‘invited to a conference', which was Smith's expression, on the following day. Smith rang me up also; he wanted me there for the first morning (he assumed that the interrogation would go on for days) in order to retrace once more the facts of how Sawbridge first entered Barford.

In past interrogations Smith had questioned Sawbridge time and again about his movements, for those days and hours when Smith was certain (though he could not prove it in a court) that Sawbridge had walked down a street in Birmingham, watched for a man carrying two evening papers, exchanged a word, given over his information; and this, or something close to it, had happened not once but three times, and possibly four.
