but in another half-hour--in less--the tide will be racing over this
very spot, and we shall be gone." Her voice vibrated; she cast a glance
behind. "One false step," she said, "too sharp a turn, too wide a curve,
and we'd have been in the quicksand! It's like that all over. It's life,
and it's full of danger, whichever way we turn."

He looked at her curiously. "Why, what has come to you?" he said.

She caught her breath in a sound that was like a sob. "I don't know,"
she said. "It's being so madly happy that has frightened me. It can't
last. It never does last."

He smiled upon her philosophically. "Then let us make the most of it
while it does!" he said. "Tonight will pass, but--don't forget--there is
tomorrow."

She answered him feverishly. "The moon may not shine tomorrow."

He laughed, drawing her to him. "I can do without the moon, queen of my
heart."

She went into his arms, but she was trembling. "I feel--somehow--as if
someone were watching us," she whispered.

"Exactly my own idea," he said. "The moon is a bit too intrusive
tonight. I shan't weep if there are a few clouds tomorrow."

She laughed a little dubiously. "We couldn't cross the quicksand if the
light were bad."
