Which author wrote the 'Alex Cross' series?

Which author wrote the Alex Cross series? James Patterson wrote the series.

Patterson introduced Alex Cross in Along Came a Spider, published in 1993. Cross is a Washington, D.C., police detective and forensic psychologist who tackles serial killers, kidnappings, and other high-stakes crimes while trying to protect his family.

The character’s appeal comes from the combination of procedural investigation and personal drama. Cross is also a father, widower, and former FBI agent, and many stories examine the tension between his dangerous work and his responsibilities at home. His grandmother, Nana Mama, and his children are recurring parts of the series.

A common mix-up is assuming that every book is written solely by Patterson. He has collaborated with other writers on some later entries, but James Patterson is the creator and credited author of the Alex Cross series. The books have also been adapted into films starring Morgan Freeman and Tyler Perry, as well as the television series Cross.
