Caitlin sat back. “The case of the backdoor dildos. Take that, Hardy Boys.”

Lakshmi went on. “I went back to the bushes and waited. There weren’t any more dongs, but around two AM …” She found a video, hit “Play.”

Caitlin watched shaky video taken through an evergreen. Lanky Frodo opened the grill, grabbed five sealed envelopes, then went inside.

“So we’re watching Frodo’s apartment?”

Lakshmi nodded. “The farmer’s son has three bedrooms all to himself.” She pointed to the SUV in the space closest to his apartment. “His car hasn’t moved all night. It’s the blue Expedition, same one he drove the night Kieran and Dave came to get Angela. Can we call Greenwood now?”

“Since they’ve separated the sale from the delivery, we can’t draw a direct line to drugs. The real question is where the money goes. We know that Kieran, Dave, Frodo, and his older brother Adam are all paid through third-party corporations. How would you get cash to the corporations? Something that no one would question?”

“Could it be a charity?”

Caitlin nodded. “The collegiate Greek system is built on the idea that all sponsored events are charitable in some way. Car washes, the dance marathon—”

“STD awareness?” Lakshmi looked up wide-eyed. “Frodo’s the fraternity’s treasurer. David was too.”

“Great, it all fits together. Say BPD pulls our dildo over and asks why he’s got so much cash. Dildo says the fraternity treasurer gave him an envelope after an organized function. Was there a cover charge for last night’s party?”

“Two bucks for the STD awareness thing. Would that be enough?”

“The amount wouldn’t matter. Our supposition is that they’re delivering weed with organic vegetables. The cover charge probably does go to a legitimate cause, but the money in the envelopes pays for the weed. The time between delivery and payment is obfuscated by the collection of money tied to the charity event.”

“And the cash gets back to Frodo. Could he launder it through the fraternity?”

Caitlin shook her head. “Risky. Could trigger an audit from the national chapter. Wasn’t there some sort of charity associated with the farm?”

“Yes, the Delta Omega Tau Alumna Philanthropic Association. If they send the money to the charity, then the charity must pay out to the farm, or at least the associated corporations.”

“Which sends the money to the shareholders. The drugs are the key. We need to follow trucks from the farm to the houses, see which deliveries are followed by events and if the money makes it back to Frodo.”

“Then we go to Greenwood?”

“Yep. I only hope we don’t have to wait until next weekend. It might be too late for today’s deliveries.”

“Oh, Caitlin,” Lakshmi said, pulling up a calendar on her computer. “We’re building up to Little Five. There are parties every night.”
