"Mr. Hume is great in mysteries, but almost excels himself in the complications of this carbuncle clue. It is brightly and briskly written, and goes on without a hitch or momentary loss of interest from beginning to end. The actors are admirably described. It is the ordinary man and woman that Mr. Hume brings on the stage, and he pulls the wires so deftly that it is with a sigh of regret that we close the book. The publishing world has been inundated with detective stories recently, but if all were so good as 'The Carbuncle Clue' there would not be much reason to complain of the fashion."--_Manchester Courier_. "One of the best detective stories that have appeared for a long time."--_Manchester Guardian_. "The whole plot is very ingeniously contrived. The interest never flags, and, together with the mystery, is kept up to the very end of the story."--_Glasgow Herald_. "In 'The Carbuncle Clue' the author elucidates with his accustomed skill a highly mysterious murder. The story is thrilling and ingenious."--_Yorkshire Post_. "Mr. Fergus Hume is a wonderful producer of books, and he proves himself the possessor of considerable resource, while he is also very versatile. 'The Carbuncle Clue' will be read with avidity by lovers of this particular class of work, while it will also be found to contain a goodly share of attraction for the general novel reader."--_Western Daily Mercury_. "For some time past the feeling has been that the detective story has had its day, living only in the memory of the immortal Sherlock Holmes. After perusing the mystery of 'The Carbuncle Clue,' however, we feel inclined to change our mind. Mr. Fergus Hume has a more than ordinary talent for the making and unravelling of enigmas."--_Liverpool Mercury_. "There are few weavers of mystery like Mr. Fergus Hume. In 'The Carbuncle Clue' his best qualities as an adept in the art of mystification are apparent. He is a magician in mystery and a wizard in working up a sensation without divulging the denouement until the opportune moment."--_Newsagent_. "A splendid story, and the identity of the murderer of the unknown man so mysteriously found stabbed to death in the chambers of a man about town is cleverly concealed until the last. There is not a dull line in the book, and the interest is never for a moment allowed to flag."--_Blackburn Times_. "A story replete with sensational excitement from the first to the last. In our opinion it is one of the best novels he has yet produced."--_The People_. "A peculiar faculty is necessary for the composition of a really ingenious story of the detective type, and Mr. Fergus Hume undeniably possesses it in an unusual degree. 'The Carbuncle Clue' is a really clever piece of work of its school. The mystery suffices to keep the reader on the alert till he comes to the final page."--_Court Journal_.
