Eager to increase his bets against subprime mortgages, the investor, John A. Paulson, canvassed firm after firm, looking for new ways to profit from home loans that he was sure would go sour.

Only a few investment banks agreed to help him. One was Deutsche Bank. The other was the mighty Goldman Sachs.

Mr. Paulson struck gold. His prescience made him billions and transformed him from a relative nobody into something of a celebrity on Wall Street and in Washington.
