THE MYSTERY OF THE SECRET ROOM. Being the Third Adventure of the Five Find-Outers and Dog.

First edition, first printing. Publisher's original red cloth with titles in gilt to the upper board and spine, with magnifying glass and fingerprint illustration in gilt to the upper board, in the J. Abbey illustrated dustwrapper. With nine black and white illustrations by J. Abbey. A very good copy, the binding firm, the spine slightly rolled, the cloth bright with mild toning to the board edges. The contents are clean throughout, and without inscriptions or stamps. Very light spotting to the fore-edge. Complete with the rubbed and nicked original dustwrapper, which is mildly toned to the edges and spine (the red lettering on which is faded to pink).

An attractive example of the third volume in the 'Five Find-Outers' Series.
