Remember when typewriter print was as regularly examined and written about in crime stories as fingerprints are today?  Yes, well his first book, Call for the Dead, first published  in 1961,by John Le Carre, took me back.  

Call for the Dead
By John la Carre, 1961
176  pages – 4h 34m
Rating 8.75,  Non-fiction spy tale

There are two typewritten letters with handwritten signatures involved.  As a matter of course George Smiley (the protagonist of a short but important series) notices that the print type shows they were produced by the same typewriter. 

This is John Le carre’s first  published novel so it’s the opener for George Smiley and his series. There are 4 books here, 

I have read a few of John le Carre’s books before and they’re good – I was in the mood. Sad to say this one starts very slowly, steadily builds tension and action, and then it’s over and the we’re back to slow.
