" Thrillers" StR,—Mr. A. A. Milne makes the common error

of describing detective novels as " thrillers." Strictly speaking, the work of Miss Agatha Christie and others comes into a very different category. Thrillers, in the strict sense, are " shockers ": The Thirty-nine Steps is the first example that comes to mind.—Yours, &c., SYDNEY HORLER. 10 The Beacon, Exmouth, Devon.
