After Case withdrew from active involvement in the Firm, he gave his desk to his long-term secretary, Katherine Clarke, who passed it on to her nephew, William Clarke. Carol Grajeda, a godchild of Mr. Clarke’s wife and the Firm’s manager of legal assistants, was told about the desk by Mr. Clarke a number of years ago and, when she learned in 2016 that Duane Wall was working on a history of the Firm, she shared with him the desk’s history.
