When an advert appears in the newspaper for children to take part in a secret mission, children everywhere sit a series of odd tests. In the end, just Reynie, Kate, Sticky and Constance succeed. They have three things in common: they are honest, talented and orphans. They must go undercover and work as a team to save themselves, but also the world.

Checkmate! These fun-filled brain teasers will increase your skill. Each chessboard puzzle has its pieces in a specially conceived difficult arrangement. You must complete a given task in a specific number of moves: "White to play and mate in five moves", for example. Some puzzles sharpen both your defensive and offensive acumen, and many focus on your endgame-the most important phase of chess. Solutions are in the back.

It's a puzzle lover's delight! Start with a bunch of horizontal and vertical lines, and then, with all the logic, concentration, and patience you can muster, get hours of pleasure as pictures appear from your own kind of magic. It's easy to master the codes for the blank and black squares. Before you know it, you'll collect 78 different fun images, including Einstein, Elvis, Marilyn Monroe, and Honest Abe, as well as the Sphinx, a skull, a flag, and a dinosaur.

If you are looking for the ultimate in logic puzzles that require pure deductive reasoning then this is the comprehensive collection for you. Even if you are new to logic puzzles, the startlingly simple instructions and crystal clear grids provide an easy introduction to this totally absorbing and intellectually stimulating pastime. Every puzzle is a whodunnit in its purest form with each grid being a scene of crime, each digit representing a potential suspect and each clue providing vital forensic evidence. However, unlike those misleading murder mysteries, there are no lateral-thinking conundrums, no ambiguous instructions, no contradictory revelations and no requirement for specialist knowledge. By determining means, motive and opportunity as well as moving from the possible to the probable to the provable, every 'crime' contained herein can be solved by using pure intellect and reason: all you need is the perception and perseverance to identify and pursue the right line of enquiry.
