Two brothers, one a successful accountant, the other a prominent solicitor commit suicide at exactly the same moment though they lived miles apart. A macabre coincidence? Perhaps, but Inspector Goff doesn't necessarily believe in coincidences. Neither does Roger Bennion, who first proves that the deaths were murder, and then finds himself trying to prove the innocence of the nephew of one of the brothers, towards who all the evidence points. But can he, with no real clues and no other suspects discover who the real murderer is?
