The young British detective is back in this third adventure. I previously reviewed Book 2: MURDER AT THE MUSEUM. Agatha is a sharp thinker with an eye for details, just what a world class sleuth needs.

At age 14 Agatha is the newest recruit for the Gatekeeper’s Guild, a secret London underground crime-fighting organization. Her mum also worked for the organization until disappearing seven years prior and is presumed dead. Agatha is desperate to find out what actually happened. But now she has her first case. An assistant at the National Gallery of Art has gone missing and Agatha is set off to investigate.

No worries if you jump into this book first. The past is flawlessly woven into the new story and you’ll never feel lost. Best friends Liam and Brianna have returned along with a new character—Arthur—an older boy Agatha is paired with to help in her first official investigation.

Despite the length of over 350 pages the pace is perfect, full of mystery, intrigue, and mystery. The twists and turns along with trying to figure out who the bad guys really are make this a compelling read.

Here’s the scoop from Harper Collins:

A third mystery for thirteen-year-old Agatha Oddly – a bold, determined heroine, and the star of this stylish new detective series.

As the youngest and newest recruit to the gatekeeper’s guild, Agatha Oddlow know she’s got a lot to prove – not least because her mother was such an important member of the secret society.

So, when an assistant at the National Gallery goes missing, Agatha begins investigating. Soon she uncovers a plot bigger than she could ever have imagined. As Agatha delves deeper and deeper into the mystery, she’s not sure she’ll ever get to the bottom of it all…

Yes, the characters are a bit older than what you typically find in middle grade lit, but all the action and relationships never stray into YA territory. This one is well worth your time. The London locale and fun interactions within each scene make for great summer time escapism—or any season for that matter!
