"The Terriford Mystery" opens with a very exciting cricket match in which a famous Australian team is beaten by one run. The host on that occasion was Henry Garlett, and it was he who, with a brilliant catch, won the match for the English team. The reader knows, therefore, that no matter how black the circumstances may be it was not Henry Garlett who poisoned his invalid wife while the match was in progress. The case against him proceeds with growing interest, and with more circumstantial detail until the very end.
