This guy was high on Greg’s suspect list. He was German, though he had left in the mid-1930s and gone to London. He was an anti-Nazi but not a Communist: his politics were Social Democrat. He was married to an American girl, an artist. Talking to him over lunch, Greg found no reason for suspicion: he seemed to love living in America and to be interested in little but his work. But with foreigners you could never be quite sure where their ultimate loyalty lay.
