“It will be necessary, nevertheless, to temporarily hide our true suspicions and attribute this crime to some unknown assassin,” Nick pointed out impressively. “Otherwise, Garside, her arrest would become imperative. I will take all the responsibility for deferring it, pending further investigations, but you must agree to coöperate with me.[Pg 13]

“Coöperate with you?” questioned Garside. “What do you mean? I don’t quite get you.”

“I mean that, having confided in you and informed you of my suspicions, you must agree not to disclose them,” Nick explained. “Otherwise, if I defer doing so, you would put me in wrong.”

“Ah, I see,” Garside exclaimed, eyes lighting. “In other words, Carter, you want me to keep my trap closed, or else agree with whatever views you see fit to explain.”

“Exactly,” Nick nodded.

“Enough said. You may depend on my doing so,” Garside hastened to assure him.

“Very good. Leave me to hand out statements consistent with the superficial circumstances, then, and to dig out the true facts from under the surface. That may take time, several days, possibly several weeks. In the meantime——”

“Mum’s the word, Carter, in so far as I am concerned,” Garside earnestly interrupted. “I understand you perfectly. I will be as dumb as an oyster. Take it from me, Carter, you can rely upon my secrecy and discretion.”

“Good enough,” Nick declared, extending his hand. “Shake. Sooner or later, Garside, I will repay you in some way for all this.”
