The first sixty-three puzzles in this collection have the form:

In a certain bank, the positions of cashier, manager and teller are held by Brown, Jones and Smith, although not necessarily respectively. The teller, who was an only child, earns the least. Smith, who married Brown's sister, earns more than the manager. What position does each man fill?

Most of the rest are arithmetic problems where some of the digits are absent or represented by letters. For example, number ninety-two is

SPEND
- LESS
----------
MONEY

Solutions to all of the puzzles are given at the end.
While the puzzles require some thought, none is of the extreme stumper variety. By using a pencil and paper and working through the possibilities, all can be solved in a short period of time. Puzzles like this are excellent mental fodder and a good way to pass the time productively. In general, I enjoy working such problems and had a lot of fun with those in this book.
