The CEO EP.38

EP.38 · An expert tells Anna that the substance found in Lucas's system is rare but available on the black market, so someone in the building could have obtained it. Trace amounts were found on documents handed to Lucas shortly before he collapsed, and a coffee mark on them was tainted with the poison, suggesting whoever handled the poison also handled the files. Armed with this, Anna is certain Nathan, Jessica and Daphne are all involved and tells the unconscious Lucas to hold on a little longer.
