"Charming is the one word to describe this volume adequately. Dr. Doyle's crisp style and his rare wit and refined humor, utilized with cheerful art that is perfect of its kind, fill these chapters with joy and gladness for the reader."--_Philadelphia Press_. "Bright, brave, simple, natural, delicate. It is the most artistic and most original thing that its author has done.... We can heartily recommend 'A Duet' to all classes of readers. It is a good book to put into the hands of the young of either sex. It will interest the general reader, and it should delight the critic, for it is a work of art. This story taken with the best of his previous work gives Dr. Doyle a very high place in modern letters."--_Chicago Times-Herald_. _UNCLE BERNAC. A Romance of the Empire._ "Simple, clear, and well defined.... Spirited in movement all the way through.... A fine example of clear analytical force."--_Boston Herald_. _THE EXPLOITS OF BRIGADIER GERARD._ _A Romance of the Life of a Typical Napoleonic Soldier._ "Good, stirring tales are they.... Remind one of those adventures indulged in by 'The Three Musketeers.' ... Written with a dash and swing that here and there carry one away."--_New York Mail and Express_. _RODNEY STONE._ "A notable and very brilliant work of genius."--_London Speaker_. "Dr. Doyle's novel is crowded with an amazing amount of incident and excitement.... He does not write history, but shows us the human side of his great men, living and moving in an atmosphere charged with the spirit of the hard-living, hard-fighting Anglo-Saxon."--_New York Critic_. _ROUND THE RED LAMP._ _Being Facts and Fancies of Medical Life._ "A strikingly realistic and decidedly original contribution to modern literature."--_Boston Saturday Evening Gazette_. _THE STARK MUNRO LETTERS._ Being a Series of Twelve Letters written by Stark Munro, M. B., to his friend and former fellow-student, Herbert Swanborough, of Lowell, Massachusetts, during the years 1881-1884.
