Death at the Bar (1940)

After an evening of friendly darts and vintage brandy, a distinguished, although amorous, barrister is in no condition to drive--or walk. The poor fellow's expired--leaving one less lawyer in the world. Everyone in the cozy pub swears that the untimely death was caused by a dart that punctured the victim's finger. But to Inspector Roderick Alleyn, the "accident" was really a case of murder.
