Father Brown is only too happy to interfere with the work of the police in solving tricky criminal cases, usually with resounding success. That's why the clergyman is transferred to a sleepy island called Abbott's Rock. At first, nothing happens there, but somehow Father Brown seems to be attracted to crime: Soon a gang of thieves is up to no good on the island. So Brown makes the headlines again, and is punitively transferred once more. This time he finds himself in a quiet Irish millionaire community.
