Stierlitz Sabotages the Bern Separate Peace
In spring 1945 SS Obergruppenführer Karl Wolff, with Himmler's backing, secretly negotiated in Switzerland with Allen Dulles of the OSS over a separate surrender in Italy. Stierlitz, a Soviet agent embedded as an SS Standartenführer, is ordered to find out who is talking to the West and to wreck the talks. He does it by feeding evidence of the contacts to Himmler's rival, Martin Bormann, and by getting word to the Allied side that the channel is exposed, so Nazi infighting and Allied suspicion kill the deal.
