"I really can't say. But I don't see why you should be afraid of it in any case. To judge by the size of it, I shouldn't say it could be a very dangerous explosive."
She smiled again with obvious reluctance, and began to study the address on the packet. It was written in a very minute hand.
There followed a pause; then with abrupt resolution Olga's fingers began to work at the outer covering.
Nick watched her, amusement on his yellow face. "I'm not quite sure that two hands are better than one when they shake like that," he observed. "Ah, here comes the dedication!" as a tiny strip of paper fluttered from Olga's fingers. "It reminds me—vividly—of my own courtship. Quite sure you don't want me to go?"
"Nick!" she protested, with burning cheeks. "It's very horrid of you to laugh. Do you know what it is?"
"I can almost guess," he said, as a small leather case emerged from the paper. "I've seen 'em before."
Olga opened the case. It was lined with white velvet, and in the centre of it there flashed and glittered a diamond and emerald ring.
"Hullo!" said Nick.
Olga looked up at him with gleaming eyes. "Nick! How—how dare he!"
"It is pretty daring certainly," agreed Nick. "It's a valuable trifle—that."
