rd,' he announced breezily. 'Alan Howard of the old Diaz
Rancho. Glad to know you both.'

'It is a pleasure, I am sure, Mr. Howard,' said the professor. 'But,
if you will pardon me, at this particular time of day----'

Alan Howard laughed his understanding.

'I'll chase up to the pool and give Helen a drink of real water,' he
said lightly. 'Funny my mare's name should be Helen, too, isn't it?'
This directly into a pair of eyes which the growing light showed to be
grey and attractive, but just now hostile. 'Then, if you say the word,
I'll romp back and take you up on a cup of coffee. And we'll talk
things over.'

He stooped forward in the saddle a fraction of an inch; his mare caught
the familiar signal and leaped; they were gone, racing away across the
sand which was flung up after them like spray.

'Of all the fresh propositions!' gasped Helen.

But she knew that he would not long delay his return, and so slipped

the act of brushing her hair. Was she to get an explanation of last
night's puzzle? Was Mr. Howard the man who had lighted the other fire?

The professor's taciturnity was of a pronounced order this morning.
Now and then as he made his own brief and customarily untidy toilet, he
turned a look of accusation upon the big Colt lying on his bed. Before
drawing on his boots he bestowed upon his toe a long glance of
affection; the bullet that had passed within a very few inches of this
adjunct of his anatomy had emphasized a toe's importance. He had never
realized how pleasant it was to have two big toes, all one's own and
unmarred. By the time the foot had been coaxed and jammed down into
his new boot the professor's good humour was on the way to being
restored; a man of one thought at the time, due to his long habit of
concentration, his emotion was now one of a subdued rejoici
