Your favor of even date to hand and contents noted. The last delivery of steel was to time but we have had warning from the railway authorities that labour troubles at the docks are likely to delay future consignments. If you don’t mind we should prefer to settle the question of future delivery by Nov. 27 as we have a board meeting on the 30th inst. While we fully appreciate your own difficulties with labour at home, you will understand that this is a question which we cannot afford to adjourn _sine die_.

Euan MacTavish folded the letter again and handed it back to Mary. “That doesn’t take me any farther,” he said. “What do the police think of it?” “They haven’t seen it,” was the girl’s reply. “I took it without them knowing.

I’ve knocked about a good bit and know something of the world, I believe. Suppose you tell me all about it ...” Mary Trevert hesitated. Then she said, her hands nervously toying with her muff: “We believe that Robin Greve—you know whom I mean—had a conversation with Hartley just before he ... he shot himself. That very afternoon Robin had asked me to marry him, but I told him about my engagement. He said some awful things about Hartley and rushed away. Ten minutes later Hartley Parrish committed suicide. And there _was_ some one talking to him in the library. Bude, the butler, heard the voices. This afternoon I went down to the library alone ... to see if I could discover anything likely to throw any light on poor Hartley’s death. This was the only letter I could find. It was tucked away between two letter-trays. One tray fitted into the other, and this letter had slipped between. It seems to have been overlooked both by Mr. Parrish’s secretary and the police ...” “But I confess,” argued the Major, “that I don’t see how this letter, which appears to be a very ordinary business communication, implicates anybody at all. Why shouldn’t the police see it?...” “Because,” said Mary, “directly after discovering it I found Bruce Wright, who used to be one of Mr. Parrish’s private secretaries, hiding behind the curtains in the library.
