While initially it was thought that we were dealing with a sudden death, officers became increasingly suspicious of the circumstances.
"At this stage our inquiries lead us to believe that this may not have been a natural death and a murder inquiry was launched on Monday."
Officers appealed for information from anyone who saw or was in contact with Ms Levey between Sunday at 12.30pm and Monday.
People were also sked to come forward if they saw a blue Vauxhall Vectra parked in a lay-by across the road from Cherry Tree Cottage on Sunday afternoon or early that evening.
