"It's an old wound in my thigh," Lefroy explained. He was just a little chagrined to discover that his host had so easily detected him. Frobisher's superior cleverness always angered him. "It is my amusement to spot the various women, and I have located most of them. But there is one! Ciel!"
"One that even meets with your critical approval! Good. She must be a pearl among women. Point her out to me and let us see if our tastes agree."
Lefroy's eyes glittered behind their mask as they swept over the reeling crowd. A moment or two later and he just touched Frobisher on the arm.
"Here she comes," he whispered. "On the arm of General Marriott. No mistaking his limp, and his white hair like a file of soldiers on parade. What a costume and what a cost! That scarlet band across her brow over the mask is wonderfully effective. That woman is an artist, Frobisher. And she has the most perfect figure in Europe. Who is she?"
Frobisher made no reply; he was studying Isa Benstein's costume—lustrous black from head to foot, with white seams fairly covered with rubies. There were rubies all over her corsage, bands of them up her arm, a serpent necklace round the milky way of her throat. The whole thing was daring, bizarre, and yet artistic to a point. The scarlet band across the brows struck a strong and vivid note. The rubies were not so bright as the woman's eyes. As she came nearer the tangle of blossom across her bosom showed up clearly. Lefroy gasped.
"A mystery in a mystery," he said. "She is wearing the Cardinal Moth. Who is she?"
Frobisher laughed, and protested that each must solve the problem for himself. He liked to puzzle and bewilder Lefroy, and he was doing both effectively at the present moment. The Count would have liked to take the little man by the shoulders and shake him heartily.
"I believe you know who she is," he growled. "Come, Frobisher, gratify my curiosity."
"I will refresh it if you like," Frobisher said with one of his sudden grins. "I am not positively sure, but I fancy I can give a pretty shrewd guess as to the identity of Madame Incognita. But would it be fair to give her secret away before supper-time? Patience, my fire-eater."
The lady of the rubies passed along leaning on the arm of her companion. She gave one glance in Frobisher's direction, and Lefroy looked eagerly for some sign of recognition. But the dark eyes were absolutely blank so far as the master of the house was concerned.
