3rd in the series, "The Inscrutable Charlie Muffin" is yet another shining example of how a disheveled, past-his-prime, on-the-run, ex-spy can still run circles around pretty much every one with whom he engages.
Charlie Muffin, still in hiding since the unfortunate incidents in the initial stories in the series that now have him branded as a traitor to Britain, is talked into investigating the fire on a ship in Hong Kong's harbor that had been insured by his friend Rupert Willoughby. Not only does he risk exposing his identity to the authorities by traveling to HK, he also soon finds himself in the company of various island and Chinese police, the CIA, and an English diplomat he once had a disagreement with. The fire on the ship, branded by Hong Kong investigators as an arson crime committed by a couple poor imported Chinese workers, results in said workers being poisoned while in custody.
The owner of the burned ship, an uber-wealthy HK resident who we also discover is involved in a lot of shady business around the island, finds himself under suspicion by Charlie but is largely protected by his wealth, connections, and lethal associates. A CIA agent shows up, operating undercover, to try to make sense of the situation since the vessel was originally American, but Charlie continues to be concerned over his possible exposure and decides to operate on his own. Based on both speculation and logic, Charlie develops a hypothesis and charges forward to prove it.
This installment of the series moves quickly with solid writing and dialogue, a good plot, and a one-of-a-kind character. It's chock full of Charlie's peccadillos (bad fashion sense, class resentment, talking to himself, etc.) but also showcases his enormous capacity to outthink his opponents. My only issue with "Inscrutable..." is that the concluding action is dropped in our lap. It made sense and tied things together but sort of came out of nowhere. Otherwise, another Muffin winner!
