OUR BOOKING-OFFICE. (_By Mr. Punch's Staff of Learned Clerks._) _The Secret Corps_ (MURRAY) is the title of a book on espionage, before and especially during the War, every page of which I have read with the greatest possible entertainment--the greatest possible, that is, for anyone at home. To get the real maximum out of Captain FERDINAND TUCHY'S astonishing anecdotes one would, I suppose, need to be under a table in Berlin while they were being perused by the ex-chiefs of Intelligence on the other side. It is a book so stuffed with good stories and revealed (or partly revealed) mysteries that I should require pages of quotation to do it anything like justice. It can certainly be claimed for Captain TUCHY that he writes of what he himself knows at first hand, and that his knowledge, like that of another expert, is both extensive and peculiar, gleaned as it was from personal service in Russia, Poland, Austria, Belgium, France, England, Italy, Salonica, Palestine, Mesopotamia and several neutral States. Still, absorbing as his book is, it suffers perhaps from being what its publishers call "the first authentic and detailed record." One feels now and then that posterity (which gets all the good things) may score again in the revelation of yet more amazing details for which the hour is not yet. Meanwhile, here to go on with is a fund of thrilling information that will not only hold your delighted interest, but (if you make haste before it becomes too widely known) ensure your popularity as a remunerative diner-out.
