#10 in the series. Author is Margaret Sutton. John Axe Format III. Grosset and Dunlap. Copyright 1937. Print run estimated at 1943. The dust jacket front flap lists to The Secret of the Barred Window (1943). The rear flap lists to Dana Girls The Portrait in the Sand (1943) and the rear of the jacket lists to Beverly Gray's Problem (1943). The dust jacket has a "P.C.J." designation at the top front flap and a "110-150" designation at the bottom of the flap. It is intact but does have minor edgewear and bumping. Semi-glossy frontispiece - that is, for a wartime book! The frontispiece is not quite the "glossy" you see in other series books printed before wartime paper, but it is not wartime paper, it's a cut above. Green boards. There is a small impression/dent in the middle of the spine but no breaking of the board. Pink staircase endpapers. Dark blue top page block. No writing/markings except for penciled numbers and price at the right top of the front free endpaper. Small store sticker attached to pasted-down rear endpaper. No tracking, no loose, ripped or missing pages, but they are yellowing wartime paper. Corner bumping, including bump at lower right of spine. Overall, an attractive vintage book illustrated by Pelagie Doane. JB-R10
