The curious Soames had read right through the telephone directory from A to Z in quest of East 18642—only to learn that no such number was published. His ingenuity not being great, he could think of no means to learn the address of the mysterious Mr. King. So keenly had he been impressed with the omniscience of that shadowy being who knew all his past, that he feared to inquire of the Eastern Exchange. His banking account was growing handsomely, and, above all things, he dreaded to kill the goose that laid the golden eggs.

Then came the night which shattered all. Having rung up East 18642 and made an appointment with Gianapolis in regard to some letters for Mrs. Leroux, he had been surprised, on reaching the corner of Victoria Street, to find that Gianapolis was not there! He glanced up at the face of Big Ben. Yes—for the first time during their business acquaintance, Mr. Gianapolis was late!

For close upon twenty minutes, Soames waited, walking slowly up and down. When, at last, coming from the direction of Westminster, he saw the familiar spruce figure.

Eagerly he hurried forward to meet the Greek; but Gianapolis—to the horror and amazement of Soames—affected not to know him! He stepped aside to avoid the stupefied butler, and passed. But, in passing, he hissed these words at Soames:—

“Follow to Victoria Street Post Office! Pretend to post letters at next box to me and put them in my hand!”

He was gone!

Soames, dazed at this new state of affairs, followed him at a discreet distance. Gianapolis ran up the Post Office steps briskly, and Soames, immediately afterwards, ascended also—furtively. Gianapolis was taking out a number of letters from his pocket.

Soames walked across to the “Country” box on his right, and affected to scrutinize the addresses on the envelopes of Mrs. Leroux's correspondence.

Gianapolis, on the pretense of posting a country letter, reached out and snatched the correspondence from Soames' hand. The gaze of his left eye crookedly sought the face of the butler.

“Go home!” whispered Gianapolis; “be cautious!”
