“Honkaku translates as ‘orthodox’, and refers to the crafting of fiendishly clever and complex puzzle scenarios – such as a murder in a locked bedroom – that can only be solved through logical deduction. … Honkaku stories have more in common with a game of chess than some modern thrillers, which can be filled with surprise twists and sudden reveals. In honkaku, everything is transparent, … giving the reader a fair chance of solving the mystery before the detective does.” – The Guardian
