Not Quite Dead Enough by Rex Stout

"Not Quite Dead Enough" - March 1942. Archie's now Major Goodwin - very good, since he's been in the Army for only 2 months, and the idea of Army discipline...well, Archie refers to snapping to one's feet and so forth in the presence of a general as 'Rocketteing'. After clearing up 'that mess down in Georgia' (an unrecorded case of his own for Army Intelligence), his superior calls him in to ask why Wolfe hasn't cooperated when asked to work for Army Intelligence. Archie confidently assumes that the Army just mishandled Wolfe, and that he's sunk deep in his normal rut.
