The Formula

Published in 2003, The Da Vinci Code follows Harvard symbologist Robert Langdon as he investigates a murder at the Louvre that leads to a secret about Christianity the Catholic Church has supposedly suppressed for centuries. Dan Brown mixed real art history with invented conspiracy, creating a thriller that sold more than 80 million copies.

Each chapter raises a new question before answering the previous one — a trick borrowed from TV serial writing that locks readers into a cycle of suspense and partial payoff. The technique is simple, but Brown ran it with mechanical precision.
