What is the author's style in The Case for Christ by Lee Strobel?

Strobel uses his years of investigative reporting to uncover the truth regarding the reliability of the gospels based on evidence that stands the test of time. Strobel's approach is balanced. He considers all the evidence, both supporting the reliability of the gospels, as well as evidence that tries to disprove or color the accuracy of the bibliographical details found in Matthew, Mark, Luke and John. He questions experts and reaches conclusions based on facts.
