I'm not generally a fan of Christie's thrillers, having been disappointed many times over. But time and again I've found a few I enjoyed. And this standalone thriller is one of them. Perhaps it is the story, or perhaps, it is the characters. But whatever it is, this novel pleasantly surprised me at a time when I was in the mind frame never to read her thrillers again.
In this story, scientists disappear from time to time, the latest one being Thomas Betterton, and an international investigation into their disappearance is launched. In this background, a woman who is about to give up life in despair takes on a suicidal mission to try and locate Tom Betterton posing as his wife.
The story was exciting in its beginning, but as it proceeded, it became slow-paced with a lot of talking and less action. This middle part was a bit tedious and boring. However, the story picked up in the latter half, and from there on, led towards a satisfactory ending, though differently than expected. It wasn't wholly a plausible plot. But for once, it didn't affect my enjoyment. The story was slow-paced. One cannot say that it was an action-packed thriller. Yet, I was led on by such an eager curiosity to know the end results that even the slow, boring parts seem bearable.
The characters certainly added to the strength of the story. The courageous and spirited Hilary Craven brought great vitality to the story. Presented at first to the readers as a character to sympathize with, Christie takes Hilary on a journey of self-discovery as well as the discovery of what has happened to the "disappeared scientists". Not only Hilary Craven, but Andrew Peters, too, deserved our sympathy as his "mission" became known. The touch of compassion for these characters that flowed from Christie's pen made them feel real and likable.
Although this novel is first and foremost a thriller, a story of a past murder and catching the culprit run parallel to the main story which is surprisingly revealed at the end. That was a new Christie experience for me which I enjoyed.
Overall, I'm pleased with myself for having been able to enjoy this novel. I was getting tired of expressing my disappointment over and over in Christie thrillers. Although I can never be an admirer of her thrillers, this one was quite satisfying.
