Carol Hawkins, 48, offered no response to the sentence as prison guards led her out of Dublin Criminal Court.

Hawkins had been free on bail after being found guilty last week of 181 counts of writing checks from Clayton’s bank account for her own use from 2004 to 2008. Records showed she used the money to buy designer clothing, 22 thoroughbred horses, a car, university education for her two children and first-class flights.

Judge Patrick McCartan said in his ruling that Hawkins deserved a severe sentence because she had demonstrated no remorse, falsely tried to pin blame for her grandiose spending on the often-absent Clayton, and could attempt similar offenses again if not jailed.

“Nothing, frankly, could explain away the scale of this dishonesty other than the greed in pursuit of a lavish lifestyle that was no responsibility of Mr. Clayton’s,” the judge said.

Dismissing her claims that she hadn’t understood that what she was doing was wrong, the judge said, “These were crimes rooted in greed and nothing else. Whether she was a fool or clever person really matters very little.”

McCartan also ordered Hawkins to surrender the profits from a sale of a New York City apartment to Clayton to help reimburse him for his losses. The potential amount wasn’t specified in court. Her defense attorney, Ken Fogarty, said she didn’t have money hidden away overseas and would do all she could to repay the €2.8 million.

Clayton, 52, wasn’t present in court to see his longtime domestic assistant sent to prison.

During the trial, Hawkins had claimed that Clayton either authorized her expenditures or that she had paid him back by using her own money to pay his bills.

But Clayton testified he’d known nothing about Hawkins’ four-year spending spree and had given her access to his bank accounts purely so she could pay bills related to his Georgian mansion, Danesmoate, in south Dublin.

During the three-week trial, a Dublin travel agent testified that Hawkins booked one flight for her husband to Miami that cost €19,285.08 ($24,420) and another for herself to London and Cincinnati, Ohio, that cost €16,139.66 ($20,438).

Clayton testified he was stunned to discover that Hawkins spent €434,000 ($550,000) on acquiring 22 racehorses, saying he had no interest in horses or gambling.

Clayton said he first met Hawkins in 1992 when she and her husband were managing a Caribbean island hotel. He said he recruited her to keep the fridge full, pay household bills and look after the place while he was traveling. He paid her a €48,000 ($61,000) annual salary and let Hawkins and her then-husband live in the house rent-free.

Hawkins worked for him for nearly 17 years, initially as a maid and cook, until he discovered her spending spree in 2008.
