Doberman Pinscher
One of the Coe brothers is found dead in his bedroom, locked from the inside, and the other brother is found the next morning dead in the downstairs closet. There is also the clue of a wounded Doberman Pinscher, a mysteriously broken piece of priceless Chinese porcelain, and a cast of suspicious family members, servants and associates. Philo Vance solves the case based on his knowledge of dog breeding, Chinese porcelain and the annals of remarkable antique crimes.
