They carried him off, protesting. Charles and I signed the charge-sheet; and the officer locked him up to await his examination next day before the magistrate. We were half afraid even now the fellow would manage somehow to get out on bail and give us the slip in spite of everything; and, indeed, he protested in the most violent manner against the treatment to which we were subjecting "a gentleman in his position." But Charles took care to tell the police it was all right; that he was a dangerous and peculiarly slippery criminal, and that on no account must they let him go on any pretext whatever, till he had been properly examined before the magistrates. We learned at the hotel that night, curiously enough, that there really _was_ a Dr. Polperro, a distinguished art critic, whose name, we didn't doubt, our impostor had been assuming. Next morning, when we reached the court, an inspector met us with a very long face. "Look here, gentlemen," he said, "I'm afraid you've committed a very serious blunder. You've made a precious bad mess of it. You've got yourselves into a scrape; and, what's worse, you've got us into one also. You were a deal too smart with your sworn information. We've made inquiries about this gentleman, and we find the account he gives of himself is perfectly correct. His name _is_ Polperro; he's a well-known art critic and collector of pictures, employed abroad by the National Gallery. He was formerly an official in the South Kensington Museum, and he's a C.B. and LL.D., very highly respected. You've made a sad mistake, that's where it is; and you'll probably have to answer a charge of false imprisonment, in which I'm afraid you have also involved our own department." Charles gasped with horror. "You haven't let him out," he cried, "on those absurd representations? You haven't let him slip through your hands as you did that murderer fellow?" "Let him slip through our hands?" the inspector cried. "I only wish he would. There's no chance of that, unfortunately. He's in the court there, this moment, breathing out fire and slaughter against you both; and we're here to protect you if he should happen to fall upon you. He's been locked up all night on your mistaken affidavits, and, naturally enough, he's mad with anger." "If you haven't let him go, I'm satisfied," Charles answered. "He's a fox for cunning. Where is he? Let me see him." We went into the court. There we saw our prisoner conversing amicably, in the most excited way, with the magistrate (who, it seems, was a personal friend of his); and Charles at once went up and spoke to them. Dr. Polperro turned round and glared at him through his pince-nez.
