A social worker found stabbed to death inside her own home had moved into the rented property just days before she was killed, neighbours said.
Police discovered the body Laura Grace Emily Davies Jones, 31, on Wednesday after being called to an address in Woodfield Lane, Lower Ashtead, Surrey.
She had suffered serious injuries and was pronounced dead at the scene at around 2.30pm.
A police spokesman said a post-mortem examination found the cause of death to be a "stab wound to the throat".
A 33-year-old man, who had also received injuries, was arrested on suspicion of murder and was taken to hospital where he was in a stable condition, added the spokesman.
The victim had only moved in to the rented property last weekend, according to neighbours.
A van was seen delivering furniture to the house - which had been empty for some time - on Saturday.
Eleanor Deighton said: "We hadn't even met them. All we knew was that tenants had moved in and the only thing we saw was a van last Saturday.
"I suppose we thought we would meet them in the fullness of time.
"It was a fairly major shock."
