to pull a story out of the twining woodbine/front-load your title to force storytelling

let’s get started

there must have been seven other solved mysteries involving the last betrayal

there must be an imperiled female for whom dawn is the literal deadline

there must be a protagonist thrust into this because they love the imperiled female

it better have been a good and unexpected betrayal

and due to the culturally short attention spans of late we better wrap it up quick

the protagonist is a woman named joelle

she’s desperate to save deena, twin sister of her lost love ed

she’s deduced no footprints because dropped by helicopter

back-stabbing knife must have been whisked away by a drone

motive to exact revenge part-one-of-two for joelle’s falling for ed

whodunit therefore is–sorry kids

out of time

but it’ll be a better story if you write it youself
