My MC is a victim of circumstances and contributes to getting caught up in a murder on the flight deck of an aircraft carrier. He is then attacked by the murderer and suffers serious injuries during a vicious fight. The murderer escapes. The murder is translated into an accident by the service authorities, and this leaves the MC helpless. Ten years later, back in civvy street, physically and emotionally scarred, he starts to uncover troublesome clues locally which brings him in due course face-to-face again with the murderer. Would the whole flighdeck scene (set in Hong Kong harbour) hit it off as a prologue (already written and comparable to a full chapter), or bring in the background as periodic flashbacks? As there is much discourse on the efficacy of prologues, it's left me unsure. I like the idea of a hard-hitting opener, but prologue/chapter 1/flashback...? Thanks for consideration.
