I am only on page 15 of The Plot Against America by Philip Roth
And there has already been 3 references to the great number. Perhaps it is historically accurate too, I am not going to look it up, but wow. THREE 27's?
Page 3- Route 27
Page 5- A day in the Spring of 1927
Page 14- Thursday June 27th.
I am a bit freaked out! :)
