"Thee her go back to her houth?" he asked. "Well, I followed. I thaw where thee'th been, too."
"Where, then?" demanded Hetherwick, impatiently.
Goldmark jerked his head in the direction from whence he had come.
"Round that corner," he said, "you get into a regular thlum. Little thtreeth, alleyth, pathageth, and tho on. In one of 'em, a narrow plathe, where there'th a thort of open-air market, there'th a good thithed pieth of blank wall, with an iron-fathen'd door in it. Well, the woman went in there—let herthelf in with a key that thee took from her pocket. Ath thoon ath thee'd gone in, I took a clother look. The door'th fathen'd with iron, or thteel, ath I thaid—jolly thtrong. There ain't no name on it, and no keyhole that you can look through. The wall'th a good nine or ten feet high, and it'th covered with broken glath at the top. Not a nithe plathe to get into, nohow!"
"Well?" inquired Hetherwick. "She went in?"
"Went in, ath I thay, mithter, and the door clothed on her. After I'd taken a glimpth at the door I got a potht behind one of the thtalls in the thtreet and watched. She came out again in about ten minitth—looked to me, too, ath if thee hadn't had a very plethant time inthide. Upthet! And thee thet off back here, fathter than vhat thee came. Now thee'th gone into her houth again—ath you no doubt thaw. And that'th all. But if I wath you, mithter," concluded Issy, "I should jutht find out vhat there ith behind that door and the wall it'th thet in—I thhould tho!"
"That's a police job," said Mapperley once more. "If we'd only got Matherfield with us, we could——" Hetherwick paused—thinking. "Look here, Mapperley," he continued, with a sudden inspiration. "I know what we'll do! You get a taxi-cab, as quickly as possible. Drive to the police station where I usually meet Matherfield. There's another man there whom I know, and who's pretty well up in this business—Detective-Sergeant Robmore. Ask for him. Tell him what we've discovered, and ask him to come back with you and to bring another man if he thinks it necessary. Now then, Goldmark! Tell Mapperley exactly where this place is."
The Jew pointed along the street to its first corner.
"Round that corner," he said. "Firtht turning to the right; then firtht to the left; then firtht to the right—that'th the thpot. Lot'th o' little thtallth in it—a bithy, crowded plathe."
"Didn't ye notice the name?" demanded Mapperley, half scoldingly.
