I cell-phone to my buddy that I need him, and make my way back to the rear entrance to let him in. Lanky and thin, he will, I hope, be able to do what I can’t. Back in IT, he clambers onto a desk. I grab him around the legs and boost him up high enough that he’s able to raise one of the tiles and slide it out of the way. As I strain to raise him higher, he manages to get a grip on a pipe and pull himself up. Within a minute, I hear him drop down inside the locked office. The doorknob turns and he stands there, covered in dust but grinning brightly.
