Hello zita,
The wordplay for GHAST has been bugging me. Reference to Chambers, which you really must buy, or put on Birthday/Xmas list, has revealed, the following. Hope you agree with this. A SUTTEE is an Indian widow who burned herself on her husband's funeral pyre. A GHAT, as well as being a mountain pass in India and a landing stair on a riverside is also a place of cremation. So first sign of SUTTEE = S, placed inside where she would have sacrificed herself, namely a GHAT!! I like it when the wordplay works as well as the definition!
Hopefully your daughter doesn't begrudge you doing crosswords, keeps the brain active, even if the body is not as active as it was!
