The British man found dead on Bali with his throat slashed was killed on instructions from his Indonesian wife, police said on Wednesday.
Julaikah Noor Ellis admitted ordering the killing of her husband, Robert Ellis, whose body was found dumped in a ditch on Tuesday, the authorities said.
Money is suspected to be one of the motives for the murder.
Mr Ellis, 60, who was also an Australian passport holder, had lived on Indonesia’s resort island of Bali for several years.
Problems between the couple
Residents found his decomposing body early on Tuesday next to a paddy field, wrapped up in plastic and blankets.
His wife reported him missing soon after his body was found.
She was later detained by police and named a suspect in the case.
Detective Wisnu Wardana said: "Our suspicion towards the wife of the victim was first aroused when some of the victim’s friends said there have been problems between the couple for a while."
“After talking to her slowly and kindly for a while, she finally admitted it.”
Maid's boyfriend had a hand in it
The boyfriend of one of Julaikah's maids had carried out the killing, police said.
The maid admitted the murder took place in the kitchen between Sunday evening and Monday morning, authorities said.
Julaikah told police she was in her room at the time of the killing, said the detective.
The wife, two maids and the boyfriend are in police custody.
Four friends of the alleged murderer suspected of involvement are being pursued by police.
Mr Ellis had been living in a villa in Sanur, and his body was found in a village to the north of the tourist area, far from any houses.
He was originally from Britain but had been living in Australia for a long time before moving to Bali.
