Once a bottom dwelling criminal, our gallant man, Montmorency, is now teamed with Lord Fox-Selwyn as a secret agent doing work on behalf of the crown. It's Victorian England and some dark mysteries need solving. Montmorency will work his magic to solve a bombing and then will go on to seek answers to why children are going missing on a remote Scottish island. But, Montomorency has some darkness of his own to deal with in the form of his addiction to opium. His friend will seek help but will Montmorency succumb to the call of the drug or will he climb out of his dark place? For those who love Sherlock Holmes this is a valiant cousin. 368 pages Ages 9-13 (sequel to Montmorency: Thief, Liar, Gentleman)
