This novel by the legendary author of "A Purely English Murder" is considered the BEST of his works! High Court Judge Justice Barber spends his life on the road endlessly, presiding over the most serious trials in southern England. He has handed down many sentences - but who of the criminals he convicted or loved ones sent him an anonymous letter with threats? At first, Barber does not take the anonymous person's threats seriously - but soon he only miraculously manages to avoid death from poison. The police are inactive. And then amateur detective Francis Pettigrew gets down to business.
