Most probably the novel 'The Silent Voice' which was entered in the 1929
Bulletin Novel Competition under the pseudonym 'Toc H' and highly commended:
T.B. Clegg ( Bulletin 19 March 1930, p.8) refers to 'one quite good novel' in the competition which used the Russian revolution as its background and Miller describes
Many Years as 'a second novel' in the 1929 competition. Although it is listed in numerous reference sources, an exhaustive search in 2006 was unable to trace this work.
