Slow starter but a honey when on its way. It involves the murder of a particularly poisonous character, a Spanish accordion player de luxe, who has wormed his way into a near engagement to the stepdaughter of an eccentric peer. The weapon, the incognito activities of the old peer, a drug racket, an unsuspected romance -- and plenty of red herrings -- all add up to problems and more problems for Social Register Inspector Alleyn and Inspector Fox. Plenty of story interest before the solution is reached. London the setting -- the time, today.
