They don't agree on much anymore.

But as their brief summertime romance was recapped in an Anne Arundel County criminal court last week, former Maryland delegate William R. McCaffrey and 7-Eleven clerk Lilly J. Walton did find common ground on one point: that overnight jaunt to the Trump Plaza in Atlantic City last July was the beginning of the end.

It was on the way back that, depending on whom you believe, either Walton started demanding a new car from her politician friend, or McCaffrey started bartering for sex in return for the same.

In either case, it was a sign for the other to call it quits, and that is what led McCaffrey, 55, a 16-year member of the General Assembly, into court with Walton, 34, who said she only wanted a vacation, not a relationship. District Court Judge Robert N. Lucke Sr. was left to sort it out.

Lucke did not pass judgment on the issue of whose arm got twisted on the way back from the beach, but he did find, after each had bared a version of the events, that there was not enough evidence to convict McCaffrey on the criminal harassment charge filed against him by Walton in September.

When it comes to love, as the testimony showed, the truth can be elusive.

"Come on, the fat {expletive} got off," Walton snapped to her waiting daughters outside the courtroom.

McCaffrey, whose off-again, on-again decision to leave his southern Prince George's House of Delegates seat caused local political leaders as much heartache as Walton said their affair caused her, said afterward that he was glad to be rid of her, once and for all.

"We should have filed extortion charges," McCaffrey's attorney, T. Joseph Touhey, said after the trial.

It all started innocently enough, although the beginning is as murky as the end.

McCaffrey, on his way to work at the State Railroad Administration office in Glen Burnie, stopped regularly for a Pepsi and a New York Post at the northern Anne Arundel County 7-Eleven where Walton worked.

According to Walton, McCaffrey became friendlier with every visit; when she said in July that she needed a vacation, he offered the trip to Atlantic City as the perfect getaway.

"I said, 'What strings are attached?' " Walton testified. "He said, 'No strings.' I said, 'You mean you are going to take me . . . and I don't have to have sex with you?' "

And, according to Walton, they didn't even sleep together. On the way back to Maryland, however, she said, he offered to buy her a car and set up a bank account for a test-run romance; if it didn't work out after six months, they would split the money and call it quits.

She turned him down, she said, but McCaffrey would not accept the answer and began badgering her family.

McCaffrey said the initiative came from her. In his account, Walton became interested after spotting his House of Delegates license plates, handed McCaffrey her phone number and address, and encouraged him to call, and keep calling. When they missed one Friday engagement, McCaffrey said, she greeted him the next Monday by jumping in his lap and giving him a big kiss.

"Unwisely, I said okay" to the trip to Atlantic City, McCaffrey testified. "I was flattered that a young woman like that was coming on to me."

There were some other good times, he said: bingo at the Knights of Columbus, the Hulk Hogan wrestling match.

Her affection, however, was mercurial. When she found he had booked at the Claridge Hotel for their trip, she demanded his credit card number and switched the reservation to the Trump Plaza, McCaffrey said. She also demanded money frequently, as well as a car, eventually escalating the assault to screaming phone calls about problems she was having with her car registration, McCaffrey testified.

Sensing she was more interested in his wallet than anything, McCaffrey said, he tried to back out of the relationship, and sent flowers in what was meant only to be a gentle goodbye.

All of which added up to a court case, but, according to Lucke, no crime.
