"Samuel Ross, last time before formally inviting Marlon Shepherd over, you found those two investigation companies for me. Help me get in touch with their heads, and arrange for us to meet at Guo Lin's homestyle restaurant at noon. You come along too!" After hanging up the call with Khaza Zuck, Yusuf Zuck immediately dialed Samuel Ross's number again. He wanted to investigate New Era Film, but his crew wasn't up to the task—they didn't have the expertise.
Having Samuel Ross or the others play around with following, watching, or ambushing was one thing, but to have them investigate the ins and outs of a company would likely turn them into headless flies crashing everywhere. Therefore, he needed to find professionals.
Last time, without a formal invitation for Marlon Shepherd, he had Samuel Ross contact two investigation companies, and both turned out to be quite good. Judging by the feedback from the two companies, they were highly capable in their business.
