A Mission - pt 11 Who is he?

Tom Macabee motioned Clack Henderson to follow him into his study where they sat at a massive mahogany desk in two luxurious easy chairs.  Tom had a serious look on his face, and Clack, one of curiosity.  After pushing aside various articles of clutter, including blueprints, scientific instruments, and a jumble of paper, Tom set about laying the contents of Coale's pockets out on the table.  First he took out the short pen, pack of miniature playing cards, pocket knife and handkerchief.  The pen was of ancient make, the refillable type, and it looked like it had been refilled countless times.  There was an engraving on the stalk with the hardly distinguishable initials T. J.  The playing cards were Pamonian but otherwise ordinary.  Both the knife and handkerchief looked old and had the initials L. J.  Then Tom handed the notebook to Clack, who leafed through it slowly.  The letters of which the text was composed were not at all ordinary, and neither Tom nor Clack could make any sense of them.  But then came the most interesting part, Tom produced the wallet.  He laid its content on the desk one item at a time first came two tens, a five, and three ones.  Then came seven assorted ID cards:  A SS card belonging to me, I don't know how he got it.  A driver's licence belonging to a certain Sam Mintrent.  The King's birth certificate ( Is that allowed? I don't know.)  A "Province Of PAM" ID card belonging to someone named Ethel Niami.  Two credit cards belonging to respectable citizens of Legovile.  A "Licensed to conduct business and trade with foreign nations" card bearing the name Clack Henderson!

Up to this point, the room had been silent, not a word being spoken, but at the sight of his name on an ID card possessed by someone else made Clack utter an exclamation and turn inquiring eyes upon Tom.  At this, Tom drew the last of the wallet's contents from it and tossed them to Clack.  They were a collection of neatly folded receipts, bearing the customer names of several of those on the ID cards, and Clack's was used at least five times.

Tom spoke the thought that was on both of their minds.  In a low whisper he said, "Our visitor is an Identity Thief."
