About nine they all began to arrive, and by ten o'clock the house was overflowing. Ben was a capital commissionaire in a District Messenger's costume he had borrowed, with George's consent, and I do believe he enjoyed himself most of anybody. Of course at first all he had to do was to stand at the door and show people in, but he hoped that later in the evening he should have to chuck somebody out. It was likely, he thought, for all the literary world of London would be sure to be at our party. I'm sorry to say that Ben was wrong there, or else the literary people didn't come, for those that did come were as quiet as lambs. There were detectives, several of them, and although I looked very particularly at their boots, which I have always been told is the way to spot a detective, I saw nothing at all out of the common. There was a man with a cloven hoof, but then he was meant for the devil. He was masked of course, but the devil needs no domino. And _I_ knew all the time that it was the little man who interviewed me once instead of George for _The Bittern_, and got me into such a row, and very devilish of him it was, and I had no butter to my bread for a week because of him. How I was supposed to know that George hated the truth instead of loving it, I can't see, only _The Bittern_ man knew well enough, I expect! Never, _never_ again will I interfere between a man and his interviewer! There were hosts of newspaper people there; I heard two of them discussing us, sitting in the high-backed Medici seat. I managed to get jammed in behind, "powerless to move," as they say in the novels, even if I had wanted to. People _are_ careless. I heard heaps of conversations, anyhow, people even said things to each other across me, without stopping to think whether or no I wasn't one of the family. I suppose because they were masked, they felt anonymous, as if it didn't matter what they said, and it needn't count afterwards. The man I listened to was _The Bittern_ man, dressed as the devil. The woman's domino was all shot with queer faint colours, and, if any colour, sulphur colour. She was scented too, a nice odd scent. _The Bittern_ man seemed to know her. "I cannot be mistaken; am I not talking to the most dangerous woman in London?" The woman seemed quite complimented, and smiled under her mask. "Not quite, but very nearly," she said. "I am a gas. Give me a name!" "I will call you Mrs. Sulphuretta Hydrogen. How does that suit you?" "Is it a noxious gas?" she said, "for, honestly, I never am spiteful! I only speak of things as I find them, and one must send up bright copy, or one wouldn't be taken on. I tell the truth----"
