"The Christian Detective" was the codename given to a group of retired English detectives in the mid-1930s that wanted to see if they could put forward a convincing case for how Jesus Christ - a man - could also plausibly be God. They sought to forensically investigate all of the circumstances of the Christian story using their extensive detective skills and experience and put Christianity on a sound footing that would pass muster in a court of law and meet the standard of proof of being true at least on the "balance of probabilities" if not "beyond reasonable doubt". The outbreak of WWII brought the project to a premature end, and it became one of history's many forgotten stories.
In 2015, a number of practicing detectives across the world, keeping in touch via the internet, adopted the name and retained the same objective: to prove the truth of their Christian faith.
As Sherlock Holmes said, "Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth." Jesus is the "impossible" truth, regardless of how much it offends atheists.
