The Sun Chemist
The Sun Chemist is a thriller by Lionel Davidson. Plot summary

Letters in the archive correspondence of Chaim Weizmann, first president of Israel, hint that, in his profession as a distinguished organic chemist, Weizmann had stumbled on a method for the cheap synthesis of petroleum. Now, decades later, a world buffeted by oil shocks and perpetually rising prices would welcome such a chemical miracle. But Weizmann's laboratory notebooks must be found first, and an unseen and powerful enemy will stop at nothing to keep them hidden. 1976 British novels
