“Every constable in the division must be acquainted with it,” replied Dunbar, confidently. “I'll know all about that car inside the next hour!”

“If on Tuesday night you could arrange to have it followed,” continued M. Max, “it would simplify matters. What I have done is this: I have bought the man, Soames—up to a point. But so deadly is his fear of the mysterious Mr. King that although he has agreed to assist me in my plans, he will not consent to divulge an atom of information until the raid is successfully performed.”

“Then for heaven's sake what IS he going to do?”

I do not know what has taken place; but I could see that, assured of escaping the police for complicity in the murder, he would turn King's evidence immediately”...

“And you gave him that assurance?”

“At first I did not reveal myself. I weighed up my man very carefully; I measured that Soames-pig. I had several stories in readiness, but his character indicated which I should use. Therefore, suddenly I arrested him!”
