Red String - does your whodunit play fair?

Plan a mystery before you draft it: pin your whodunit's suspects and clues to a corkboard by chapter and see which clues the reader actually gets before the reveal - earnable, kept off the page, or too late - with tally marks on every suspect, a late-culprit check and suspects in name only flagged, all free in the browser. A metered fair-play reviewer then calls the book fair, thin or cheats, names a careful reader's guess, rates every clue and proposes plants by chapter that you can pin to the board.
