Agatha Raisin and something borrowed, someone dead - M. C. Beaton

Incomer Gloria French is at first welcomed in the Cotswold village of
Piddlebury.
She seems like a do-gooder par excellence, raising funds
for the church and caring for the elderly.
But she has a bad habit of
borrowing things and not giving them back, so when she is discovered
dead, poisoned by a bottle of elderberry wine, folk in the village don't
mourn her passing too intently.

Parish councillor Jerry Tarrant
hires Agatha Raisin to track down the murderer.
But the village is
creepy and secretive and the residents don't seem to want Agatha to find
who the murderer is, and Agatha's investigations are hampered by the
emotional upset of finding her ex, James Lacey, has fallen in love with
young detective Toni Gilmour.

And now the murderer is targeting Agatha!

Praise for the Agatha Raisin series:

'M.C. Beaton's imperfect heroine is an absolute gem'
Publishers Weekly

'Clever red herrings and some
wicked unfinished business guarantees that the listener will pant for a
sequel'
The Times (audio review)
