"MR. KERNAHAN has a unique record for literary manysidedness. His
detective novels have been scarcely less successful than Dr. Conan
Doyle's. His religious booklets have been the subject of more sermons
than even the works of Mr. Hall Caine and Miss Marie Corelli; and his
essays in criticism, reprinted from the _Nineteenth Century_ and the
_Fortnightly Review_, have won the approval of critics of the highest
standing, and have rivalled Mr. Augustine Birrell's in popularity."
