Ellery Queen was one of two brainchildren of the team of cousins, Fred Dannay and Manfred B. Lee. At the beginning, "Ellery Queen" the author was marketed as a secret identity. Ellery Queen (actually one of the cousins, usually Dannay) would appear in public masked, as though he were protecting his identity. Even after the cousins' identities were disclosed, their novels continued to be published under their now-famous pseudonym. TLS signed 'Manfred B. Lee,' one page, 7.25 x 10.5, Ellery Queen letterhead, August 3, 1970. In part: 'We are only too happy to acquiesce to your request and autograph the front 'cover' Danger, Men Working. We are curious as to where your copy of the script came from. Is it a copy of the playscript? (Danger, Men Working was originally written as a three-act play but was never produced on Broadway). Or is it a copy of the Paramount scenario? (We eventually sold it as a movie). In either event, where were you fortunate enough to procure it? I wonder if you could do us an immense favor. Could you have your copy Xeroxed or whatever? We desperately need a copy, since we can't locate ours! I should be glad to remit the cost in advance, or if you prefer to send me the copy and bill me, I promise solemnly to remit by return mail. Fred Dannay and I would really appreciate the favor.' In fine condition, with scattered light creasing, staple holes to the upper left corner and a tiny area of trivial soiling. RRAuction COA.
