Skin O' My Tooth

'Skin O' My Tooth' is an adventure-mystery novel written by Baroness Orczy. It features a man known as 'Skin O' My Tooth' whose real identity is Patrick Mulligan, an ugly, portly, but particularly sharp Irish lawyer who goes to great lengths (even unscrupulous ones) to get his clients off. Usually, this involves him solving the crimes himself. The nickname comes from one client who described Mulligan freeing him "by the skin o' my tooth."
