Oh, yes, it’s finally here, and it’s quite simply fabulous! I’ve been eagerly awaiting the last in the ‘Promise Falls’ trilogy, each book has ramped up my expectation for the next, and I was literally dancing in my seat when I got hold of ‘The Twenty-Three’.
Chapter one, once again is a statement of intent, two sentences, 19 words, and you know you're in for a thrilling, chilling ride. People are dropping like flies in the town of Promise Falls, Detective Barry Duckworth hasn't got time to think, let alone eat. There are surprises at every corner and the story is drenched in tension.
Linwood Barclay wields a sledge hammer full of impact, yet it’s his ability to point you in the direction of the small things, the subtle, the hidden, that I really admire. As with life, all the threads aren't left in a neat and tidy row, there are a few left unfinished, left free, to float in your mind, and creep up on you long after you've finished.
‘The Twenty-Three’ is a zig-zagging, mind-gripping, wonderfully entertaining read, and I loved every exhilarating second of it. ~ Liz Robinson
