seeking a pro bono or contingency fee entertainment law litigator in los angeles CA area

Need pro bono/contingency entertainment litigator: a wealthy man optioned rights to a "household name" novelist's books and 4 months into the contractual relationship has filed a law suit in Los Angeles which contains ridiculous (and false) allegations. He is using the cost of litigation as a tool to steal the book rights from the novelist's crippled widow as settlement. I'm told we have a case for malicous prosecution but the cost of trial will keep us from getting to that point. He wrote option checks from his rich real estate company and we're hoping a cross complaint can be filed. If interested please help! Or please refer us if you know a pro bono/contingency litigator who may be interested in looking at this case. Thank you, thank you, thank you.
