"I only saw that woman for a minute or two, by moonlight, when she stuck her face out of her car to ask the way," replied Allerdyke, "but I'll lay all I'm worth to a penny-piece that the woman I then saw is the woman whose picture we're staring at. Great Scott! So she's a famous singer, is she? You know of her, of course? That sort of thing's not in my line--never was--I don't go to a concert or a musical party once in five years." "Oh, she's great--sure!" responded Fullaway. "Beautiful voice--divine! And, as I say, things are going to be easy. I've met this lady more than once, though I didn't know that she'd any other name than that, which is presumably her professional one, and I've also had one or two business deals with her. So all we've got to do is to find out which hotel she's stopping at in this city, and then we'll go round there, and I'll send in my card. But I say--do you see, this affair's to-night, this very evening, and at eight o'clock, and it's past seven now. She'll be arraying herself for the platform. We'd better wait until--" Allerdyke's practical mind asserted itself. He twisted the American round in another direction, and called to a porter who had picked up their bags. "All that's easy," he said. "We'll stick these things in the left-luggage spot, dine here in the station, and go straight to the concert. There, perhaps, during an interval, we might get in a word with this lady who sports two names. Come on, now." He hurried his companion from the cloak-room to the dining-room, gave a quick order on his own behalf to the waiter, left Fullaway to give his own, and began to eat and drink with the vigour of a man who means to waste no time. "There's one thing jolly certain, my lad!" he said presently, leaning confidentially across the table after he had munched in silence for a while. "This Miss Lennard, or Mamselle, or Signora de Longarde, or whatever her real label is, hasn't got those jewels--confound 'em! Folks who steal things like that don't behave as she's doing." "I never thought she had stolen the jewels," answered Fullaway. "What I want to know is--has she seen them, and when, and where, and under what circumstances? You've got her shoe-buckle all safe?" "Waistcoat-pocket just now," replied Allerdyke laconically. "That'll be an extra passport," observed Fullaway. "Not that it's needed, because, as I said, I've done business for her. Oddly enough, that was in the jewel line--I negotiated the sale of Pinkie Pell's famous pearl necklace with Mademoiselle de Longarde. You've heard of that, of course?" "Never a whisper!" answered Allerdyke. "Not in my line, those affairs. Who was Pinkie Pell, anyhow!"
