I'm writing a cozy mystery similar to Agatha Christie's Manor house cases with a small circle of suspects. Most of the books I've read on the topic of mystery writing stress writing the plot in the format of a series of scenes and sequels. Furthermore, they stress that the writer creates tension from the very beginning and keep heightening the tension with twists and turns, and mainly physical conflicts with the antagonist until the ending in which the tension peaks. I find writing in scenes and sequels for a mystery, especially a cozy mystery, counter intuitive. I want my detective to approach the case and solve it in a creative, smart, and productive manner. I can't see myself writing scenes with disasters when the detective should focus on the intellectual aspects of solving the crime. The crime should be a challenge to the reader as a satisfying exercise in logical thinking. Also, there should be no room for break neck action and rising tension in which the detective is beat up or barriers are placed in his tracks all the time. The same goes for romantic subplots. I want to avoid this too. So, is it OK, acceptable, or common for cozy mystery writers to exclude writing scenes that feature conflicts and disasters? Is it OK to exclude the process of progressively making the tension worse to the end or even excluding tension all together? Of course, I know I should make the scenes interesting enough to make the reader want to continue reading the story. So, I want to write a mystery that offers the reader a satisfying opportunity to engage in a pure exercise of solving a crime using logical thinking without being distracted by unnecessary tension, disasters, and subplot dramas.
