"I have promised that, Conny."
"And, Ray, you will keep this all a secret; you will do your part without hinting to Doctor Heath your true motive, unless circumstances compel an explanation?"
"I promise that, too."
"When I sent for you, it was to ask you to warn Doctor Heath, in the most delicate way you could devise, that he was menaced by an enemy, and under hourly surveillance; but, since you have told me of this, Burrill, it occurs to me that in some way he may be mixed up in this matter, and—I have thought of a better plan."
Ray nodded, and looked full of interest.
"Your description of his manner of receiving Burrill's interference, and of his reticence throughout, makes me feel that it might be only precipitating a catastrophe if we warned him, and so, Ray, I want you, for three days, to be his constant shadow. Devise some excuse for remaining in town; thrust yourself upon his hospitality; observe any strangers who may approach him. If possible, do not let him get out of your sight, even for a short time; in three days you shall be relieved."
"By whom?"
She lifted her hand, warningly. "No questions, Ray. Can you manage all this?"
He pondered a while, then said: "I think I can; I am a pretty good actor, Conny. What do you say to my feigning illness?"
"He would find you out."
