On Edvard Radzinsky´s book Stalin

"In May Hitler was in the Balkans, and it was getting late for attacking Russia. If Hitler would attack Russia still in 1941 he would have to prepare for winter.Which means he would need millions of fur coats and that would mean that lamb meat price would go down in the markets and as well the lamb skin prices would go up. The Russian security service had not noticed anything like this happen..."

Maybe, maybe not. But Stalin did not know Hitler was sure the war would end long time before winter!
