This was one of the better boxcar children books I have listened to. They go to help set up an invention convention of a famous clock maker. We'll there they discover her books explaining how to make the clocks is missing so they set put to find it. I never would have guessed the location, so that was a nice surprise.

I got soo annoyed with Martha and how she just kicked them out like she owns the place like gosh still a good book tho

i have read all of them but could not find the first one so i just picked on to put up

I loved these books as a kid & I'm really enjoying reading through the series again. I liked the mystery & the suspense. I like how there is more than one possible suspect, who each have reasonable motive. Would recommend.

I really enjoyed this book! I often like the Boxcar books with riddles so this one was great!
