Some mysteries go unsolved.
In 1987, a treasured and unique gift that was bequeathed to the city of Bath was stolen, never to be seen again.
To get the full picture of this tale, we need to go back to the 1930s.
When Italy invaded Abyssinia (now Ethiopia) in 1935, the then emperor of the country, Haile Selassie, and his family were forced into exile.
Haile Selassie, which roughly translates to 'Power of the Trinity', and members of the Abyssinian royal family spent a major part of their exile (1936–41) at Fairfield House in Newbridge, Bath.
He then purchased the house and later donated it back to Bath.
In October 1954, as a mark of his gratitude, Selassie donated ivory tusks and a carpet to be displayed at the Guildhall.
He was also made Freeman of the City.
Lucy Powell works as a collections manager (archives) in the Bath Record Office for Bath and North East Somerset Council.
"Haile Selassie was in exile in Bath in the late 1930s after Ethiopia was invaded by Italy," she said.
"Having a head of state living here was an exceptional thing to begin with.
"There was a lot of mutual affection from him to this city and from the people of Bath to him.
"Then he came back in 1954 and spent several days here. He was made a Freeman of the City then too.
"It was a really important episode in the Guildhall and Bath's recent history."
And then, disaster struck.
On February 16, 1987, the Bath Chronicle reported the ivory tusks had been stolen.
"The theft itself was a very sad incident. This token of affection and appreciation was taken away," Lucy Powell added.
"Will still keep the plinth on which the tusks stood and the carpet he gave as a gift.
"The smashed glass case was discovered on a Monday morning.
"A lot of people would have seen them when it was kept at the Guildhall.
"Part of the building used to be a court room, so the public, witnesses and reporters even would have seen it.
"The whole thing is a bit of a mystery.
"As far as I know, nothing else has been heard of them."
Selassie died in 1975, 12 years before the theft took place.
And that is the tale of the stolen ivory tusks - one of Bath's greatest unsolved mysteries.
