Rosalind is dead, and one of 7,500 people did it.
Every resident of the town had known her. Many had reason to wish
her harm. But only one of them is guilty - and it falls to you to
find out who. This is not a novel to be read from beginning to end.
It is a case file to be worked, a puzzle to be solved, and a killer
to be caught using nothing but logic and a steady hand.
HOW IT WORKS
Inside this book you will find a complete list of all 7,500
suspects, and a set of eighteen clues. Every clue is a plain,
verifiable fact about the person who committed the crime - the
letters in their name, the length of it, the way it begins or ends.
None of them is a trick. None of them is a false trail. Taken
together, they point to exactly one person.
Your task is simple to describe and deeply satisfying to carry out.
Read a clue. Cross out every suspect it rules out. Move to the next,
and the next, watching the list of possibilities shrink with each
one. When you have worked through all eighteen, a single name will
remain uncrossed. That name is the killer.
A REAL PUZZLE, FAIRLY MADE
This is a puzzle built to respect the solver. The suspect list is
deliberately shuffled, so there are no shortcuts, no blocks of names
to skip, and no way to guess your way to the answer. Every name must
be read and judged on its own merits. And unlike many puzzles of its
kind, the solution here is guaranteed: each book is verified to
resolve to exactly one suspect, so the answer you reach through
careful deduction is the only answer possible.
There is no story to follow, no characters to keep track of, and no
prior knowledge required. What you bring to the table is patience,
attention, and the quiet pleasure of reasoning your way to the
truth. What the book provides is a case that holds together from the
first clue to the last.
WHO IT IS FOR
Find Rosalind's Killer is made for puzzle enthusiasts who want
something more absorbing than a crossword, for mystery readers who
have always wanted to do the detecting themselves, and for anyone
who enjoys pure deductive reasoning. It makes an ideal companion for
a quiet evening, a long journey, or a rainy afternoon, and a
memorable gift for the armchair detective in your life. All you need
to begin is a pen, a comfortable chair, and a sharp eye.
The suspects are waiting. The clues are on the page. The answer is
sealed at the back - but see how far you can get before you turn to
it.
One name. Eighteen clues. 7,500 suspects. The rest is up to you.
