A logic puzzle book built around a single case: identify Isolde's killer from a field of 28,000 suspects using 18 verifiable clues. It is a deduction exercise in the classic grid-and-clue tradition, scaled up far beyond the usual handful of suspects. It suits puzzle fans who like methodical elimination and long sessions rather than quick crosswords. Against typical murder-mystery puzzle books, the suspect pool and clue count make it a heavier, more deliberate solve.
