Ascension Sunday balloons are not the only things disappearing in the English village of Aidan Kirkwood. When the villagers celebrate the first Ascension Sunday Processional in fifty years, someone goes missing. A well off widow who was amongst the crowd has vanished into thin air. And she's not the only one who's nowhere to be found.
Berdie Elliott, the local vicar's wife, goes into sleuth mode as eccentric cat lovers, a secretive informant, Portuguese holidays, an enigmatic "tree" house, and tangled family dynamics all add to the perplexing affair.
