Tommy and Tuppence, whose not supposed to be there, travel to the seaside to catch German Spies during WWII. I just can't get into these characters as they are so annoying and just stumble on the truth rather than solving anything, even so its an interesting story.

Review by

Audiobook performed by James Warwick<br/><br/>Book # 3 in the Tommy and Tuppence series has our couple bemoaning the fact that they’ve been basically put out to pasture. They recall how very successful they were in ferreting out spies during the Great War (i.e. WW I), and bemoan the fact that their government seems not to want to use them this time around. Ah, but there is a small job that Tommy might help with. There is no role for Tuppence, but you can’t expect her to take THAT lying down!<br/><br/>Tommy and Tuppence are quite the pair, but the books are definitely dated. Still the intrigue is there and I was kept guessing right up to the end. Christie throws in several red herrings, a colorful cast of characters, some near misses and definite danger to keep the plot moving at a fast pace and the reader off balance. <br/><br/>James Warwick does a fine job narrating the audio version. <br/>
