Indeed it was not. Very nice puzzle -- lots of 'action' in the clueless grid. And I liked the solving path -- this one seemed to have a fairly logical 'plot' to it, as opposed to just stumbling into random deductions.

I've got no idea if that's just a matter of individual perception or not....maybe they all have a logical solving path, and I just haven't been finding them very often!
