Book excerpt: Sherlock Holmes isn’t the only detective in London—Andrew Tillet and Sara Wiggins at your service! Andrew Tillet can hardly believe his luck. Only one year ago he landed in London completely unaware of his real name and identity, or that his mother was the beautiful and accomplished actress Verna Tillet. Now that he and Verna have been reunited and Sara and her family are well provided for, it seems like all their dreams are coming true. But no amount of good fortune can spoil Andrew and Sara’s taste for adventure, and when they run across an unusually observant policeman named Constable Wyatt, they have a feeling they’ll be seeing him again. When they do, it’s sooner than expected. The fabulous Denham diamonds have been stolen from Verna Tillet’s own bedroom, and Andrew, Sara, and Constable Wyatt jump on the case. But how did the thief get into the second-floor window without a ladder? When Andrew and Sara find a fresh corpse on their lawn one night, only for it to disappear before the police arrive, can they convince anyone to follow the clues and recover the jewels before it’s too late?
