As cool weather starts to creep in and nighttime falls a bit earlier, it’s the perfect time of year to curl up with a cup of tea and lose yourself in a good mystery. Which is probably why the first week of October is Mystery Series Week. 

The best part about reading a mystery series is getting to really know the quirks and idiosyncrasies of the starring and recurring characters across multiple books, and getting a chance to watch the author grow in real time. Plus, many mystery series have overarching storylines and themes in addition to the whodunit at the centre of the novel: Will the lead detective ever solve the murder of his family? Will the forensic anthropologist ever catch the killer that got away? Will the two bantering partners ever admit their feelings for one another?

Ranging from YA to classics to modern detectives, here are some of the KWL team’s favourite mystery series.
