London's River Thames hardly seems to be the location where a person might expect to see a classic lake monster or sea serpent.
Yet, the river has been the site of at least one such encounter.
Or, at least according to a guy named Colin Perks, it has.
I met Perks a few years ago, when he told me a long and convoluted story about his alleged knowledge of diabolical activity in the ancient English town of Glastonbury that was connected with the legends of King Arthur and the actions of a monstrous gargoyle that protected the final resting place of the renowned king.
The story was told in my book Three Men Seeking Monsters, and more than half a decade after I first heard Perks' story, I still don't know what to make of it.
Indeed, the story became even more bizarre when Perks later claimed to have photographed a very small serpent-like beast in London's River Thames, and in a stretch of the river that ran right past British Intelligence's MI6 building.
Whether it actually shows nothing stranger than a log, a real serpent-style entity of some type, or something else entirely, I know not.
But for what it's worth, here's Perks' photo, reproduced above.
