Hi! I've been trying to find a book (series?) I read as a child, maybe around 2013-2016. It was a mystery chapter book, with three children being the main characters, I think 2 boys and a girl? I'm like 70% sure one of the boys' names had 3 letters. They solved mysteries around their city, like at a museum or cruise ships. The titles were always structured as The ____ that _______. Thank you!
