Here a long interchange of signals took place, and even whispering behind a hat.

"Well, Miss, I say ten, and that quite enough till you has time to judge. But Balak say nothing under twenty, considering all the beer, and some of it country brewers'--"

"Your advice is better than Balak's; I agree with you on that point; and I will take it in preference. Here are ten pounds." He looked rather taken aback, but could not well get out of it. Balak smiled grimly at him.

"If what you tell me proves really valuable, I will give you a cheque for another ninety ere long, and the residue hereafter: but not another farthing, if you keep me in this suspense. Do I look likely to cheat people of your class?"

"No, Miss, we hopes not; nor of any other class, I dare say. Still there be so many rogues in the world--"

"You have taken my money; speak on."

What they told me at wearisome length, and with puzzling divergence, and quantities of self-praise, need not occupy many lines. They had traced the Jelly-corses, as they called Della Croce, from Somers Town to Lisson Grove, where they stayed but a very short time, Lepardo Della Croce, under some fictitious name, giving lessons in French, Spanish, and Italian, at schools in Portland Town and St. John's Wood. But he only seemed to play with his work, though he never broke any engagement to which he really pledged himself. He was always reserved and silent, accepted no invitations, and gathered his real subsistence by night at chess-clubs and billiard-rooms, where his skill was unequalled. His only friends were Italian refugees, his only diversion the vivisection of animals. It must have been about this time that he saw the newspaper paragraph, and did what he did to me. Then he changed his name again, and lived awhile in Kensington; he had been in London years before, and seemed to know it well. Here a nobleman, whom he had taught some new device at billiards, took him up and introduced him to a higher class of pupils, and obtained him some back-door palace appointment. He dubbed himself "Professor," and started as Dr. Ross. But still he missed the excitement and change of his once adventurous life, and several times he broke loose, and left his household, for weeks and months together. Then the two lovely children, whom all admired but none were allowed to notice, were attended wherever they went, by a dark-browed Italian woman. Suddenly they all left Kensington, and went to live at Ball's Pond; the reason being some threatened exposure of the Professor's cat-skinning propensities. His love of vivisection had become the master-passion, and he would gratify it at all hazards. There is to some natures a strange fascination in the horrible cruelties perpetrated under the name of science. Through its influence he even relaxed his strict reserve a little, and formed the acquaintance of a gentleman connected with the college at Camden Town; to which suburb after a while he removed, because he found it impossible to pursue his inhuman researches under his own roof comfortably. Here, by means of his new ally, who could not help admiring his infinitely superior skill, he was appointed lecturer at several schools for young ladies, where smatterings of science were dealt in. And now he was highly respected by people who did not know him, and idolised by young ladies too clever to care for pet parsons. Of course he became conceited; for his nature was but a shallow one, and his cunning, though sharp and poisonous, had no solid barb at the end. So he sneered, and grimaced, and sniggered, and before an ignorant audience made learned men stammer and stutter, amazed at his bold assumptions, and too honest and large of mind to suspect them, at short notice.

But the skill of his hands was genuine, and his power of sight most wonderful. I have since been told--though I do not believe it possible--that he once withdrew and bottled nearly half the lungs of a dog, tubercular after distemper, while the poor sufferer still gasped on, and tried to lick his face. Oh that I were a man! How can I hear such things and not swear? All animals, except one, hated him by instinct. The only one, not sagacious enough to know him, was his fellow-man. Men, or at any rate women, thought him a handsome, lively, playful, and brilliant being. And yet, upon the honour of a lady I declare--let those who know nothing of honour despise it as an after-thought--that when he first entered my room, in his graceful and elegant way, there ran through me such a shudder as first turns the leaves towards autumn, such a chill of the spinal marrow as makes the aura of epilepsy.

Darling Judy hated him from every bristle of his body, not only through instinct, but for certain excellent reasons. The monster's most intimate friend was a gallant Polish patriot, who had sacrificed all for his country, and lived here in dignified poverty. This gentleman and his wife could only afford one luxury; and that, by denying themselves many a little comfort. They had the finest dog in London, one who had saved his master's life from the squat-nosed sons of the Czar. This glorious fellow, of Maltese family, was the father of my Giudice--whom in his puppy days the Polish exile gave to Conrad and pretty girl Isola. Slowski, now an ancient dog, had a wen behind his shoulder, which grew and grew until the Professor could scarcely keep his hands from it. But he knew that any operation, in so severe a case, was nearly sure to kill a dog so old and weather-beaten. The owner too knew this, and would not have it meddled with. Lepardo Della Croce swore at last that he would taste no food until he had traced the roots of that wen. Judy, then a pretty pup, gambolled into the room and saw his poor papa--but I will not describe what a dog cannot even bear to think of. Poor Slowski died that night, and the Pole knocked down the surviving brute, who shot him next day upon Hampstead Heath. However, the gentleman slowly recovered; but during his illness the frenzied wife overstepped the bounds of honour--according to their ideas; she took advantage of Cora, in the absence of Lepardo, and learned some of his previous crimes, by practising on the poor woman's superstition. Then she found, through the firm of Green, Vowler, and Green, that my Uncle was still alive, traced out the history of the atrocious deed, and wrote the letter which had brought me to London. Soon afterwards, when her husband recovered, she was sorry for what she had done, and opened her lips on the subject no more; at least in this country, which they soon forsook for America.

In this brief epitome, I have told, for the purpose of saving trouble, a great deal more than I learned at the time, a great deal more than Balaam and Balak would have found out in a twelvemonth. But it makes no difference: for my conclusions and actions were just the same as they would have been, if I had known all the above. "And so you see, Miss"--was Balaam's peroration--"we have had a downy cove to deal with, for all his furious temper. Lor now, I never believe any Bobby would have discovered him; but we has ways, Miss, what with the carpets and the sofys, and always knowing the best pump at the bar, gentlemen of our profession has ways that no Peeler would ever dream of. And now, Miss, the ink is on the table, and both of us wishes you joy--didn't you say so, Balak?--if you only think we has earned that cheque for 90*l.*, and the rest, please God, when the gentleman feel Jack Ketch."
