Grenier dictated this epistle from a carefully composed copy. He understood the very friendly relations that existed between Philip and his chief agent, and he thought that in adopting a semi-apologetic, frankly reticent tone, he was striking the right key.

The concluding reference to the Mary Anson Home was smart, he imagined, while the main body of the letter dealt in safe generalities.

The King of Diamonds — Part 159

Naturally, he knew nothing of the conversation between the two men on this very topic a couple of months earlier.

But Langdon's ample confessions had clearly revealed Philip's attitude, and the unscrupulous scoundrel was willing now to dare all in his attempt to gain a fortune.

The King of Diamonds — Part 159

While he was dining a telegram was handed to him:

"You forgot to send your address, but Mr. Abingdon gave it to me. So grieved you are detained. What about blue atom?

Did ever woman invent more tantalizing question than that concluding one? What was a blue atom? No doubt, creation's scheme included blue atoms, as well as black ones and red ones. But why this reference to any particular atom? He tried the words in every possible variety of meaning. He gave them the dignity of capitals. BLUE ATOM. They became more inexplicable.

In one respect they were effective. They spoiled his dinner. He had steeled himself against every possible form of surprise, but he was forced to admit that during the next three days he must succeed in persuading Evelyn Atherley that Philip Anson was alive, and engaged in important matters in Yorkshire. That was imperative--was his scheme to be wrecked by a blue atom?

Moreover, her query must be answered. His promise to write was, of course, a mere device. It would be manifestly absurd to send her a typewritten letter, and, excellently as he could copy Philip's signature, he dared not put his skill as a forger to the test of inditing a letter to her, no matter how brief. Finally he hit upon a compromise. He wired:

"Stupid of me to omit address. Your concluding sentence mixed up in transmission. Meaning not quite clear. Am feeling so lonely.

Then he tried to resume his dinner, but his appetite was gone.

In postal facilities, owing to its position on a main line, York is well served from London. At 9 P. M. two letters, one a bulky package and registered, reached him.
