BECAUSE of David a great many things happened in London one day recently. But for him, Gladys, the stenographer, could not have met Mr. Johnson, and the Paddington Murder Case would have remained unsolved. But for David, Lord Midhurst would not have escaped from Mr. Fink's clutches. Lady Hermia Medmenham, Mr. and Mrs. Rivington, Mr. Gawthorne (the author has a genius for names), and scores of other people would have gone on in a very pleasant rut,--but for David.

Mr. Mackail, whose last book, "The Square Circle", was a Book of the Month Club selection, has written a pleasant and amusing tale, almost too full of coincidence, but so cleverly written that no one feels any particular objection. "David's Day" is ingenious and entertaining, not good enough for a book club to select it, but good enough.
