The Seer smiled sweetly. He was an engaging man, and when he flooded Philippina with the light of his great eyes she thought him really as nice as anybody on earth, except Herr Andreas. They sat there long, and chatted in that peculiar vein which Philippina affected when she found herself alone with one of her male admirers. She was a born flirt, Philippina, and though she was a matron now, with a distinct tendency to grow visibly stouter on good English fare, she had still all that archness and that liveliness of manner which had captivated Florian the first morning they met her on the hill-top at St Valentin. As they sat there, exchanging a quiet fire of repartee, with many _ach’s_ and _so’s_ of very Teutonic playfulness, the lodging-house servant came up with a note, which Philippina tore open and read through somewhat eagerly. The Seer noticed that as she read it her colour deepened—such signs of feeling seldom escaped the eyes of that observant thought-reader. He noticed also that the envelope, though directed in English letters, bore evident traces of a German hand in the twists and twirls of the very peculiar manuscript. He could see from where he sat an unmistakable curl over the _u_ of Bury Street. A curl like that could only have been produced by a person accustomed to German writing. Philippina crumpled the envelope, and looked vacantly at the fireplace. The fire wasn’t lighted, for the day, though damp and dark, was by no means chilly. The Seer noted that glance: so she wanted to burn it, then! Philippina, unheeding him, poked the envelope through the bars of the grate with the aid of the tongs, but laid the note itself on the table by her side, a little uneasily. The Seer, with that native quickness of perception which had made him into a thought-reader, divined at once what was passing through her mind; she must destroy that note before Theodore returned, and she was anxious in her own soul for a chance of destroying it. Joaquin Holmes spotted a mystery—perhaps an intrigue; but, in any case, a mystery. Now little family affairs of this sort were part and parcel of his stock-in-trade; there was nothing so useful to him in life as possession of a secret. And Philippina was indeed an open book; he could read her as easily as he could read a pack of cards with the tips of his fingers. The longer he stopped, the more obviously and evidently Philippina fidgeted; the more she fidgeted, the longer he determined, as he phrased it to himself with Western frankness, “to stop and see the fun out.” Philippina grew more and more silent as time went by; the Seer talked on and on with more unceasing persistence. Meanwhile, the fog without grew denser and denser. At last, of a sudden, it descended, pitch dark, with that surprising rapidity we all know so well in our smoky metropolis. Philippina yawned; she saw there was no help for it. It was a case for the gas. “Will you ring the bell, Mr Holmes?” she asked languidly, in German.
