I spent my first afternoon back at work standing in a mystery location on Merseyside watching a bunch of French artists testing out the controls of the La Machine mystery creature.
Everything is a mystery with this one as you may have gathered by now.
The production team behind the project - which could well rival Go Superlambananas for Capital of Culture's most incredible street festival - are going to extreme lengths to protect the identity of their project.
And fair play to them.
Because when it all starts to unfold in a couple of weeks, they want it to be one gigantic surprise.
We drove to said mystery location where, over tea and digestives, it was drummed into us that we MUST NOT under any circumstances divulge the identity of the mechanical creature or what was going to happen to it.
Then, for some of us who didn't make the trip to La Machine's French workshops last month, we got our first glimpse of the mechanical marvel in all its glory.
And it's an incredible sight.
It takes a dozen people to operate it and it weighs 35 tonnes. It can also move at 3-4km an hour (there's the French for you, it has to be metric! Still, you may not want to be in a traffic jam behind it!!!)
The La Machine team have spent 12 months building the complex metal and poplar wood structure.
And telly film crews spent almost as much time yesterday afternoon trying to creatively film it without giving away what it is or where it is. We were all roped into standing around as background fodder, looking impressed.
Meanwhile designer Francois Delaroziere, all gallic sideburns and smiling shrugs, was keeping the mystery going (even with the creature in front of us) by saying cryptically: "We know something has arrived in Liverpool concerning life, machines and the city.
"We are impassioned and I hope the people of Liverpool will be impassioned as well."
Alors Francois, do you know what? I think they might well be.
