There is a theory, to which those who regularly read my reviews will know I sometimes subscribe, which says that the short story's heyday has passed and it has now put itself out to grass. This is particularly true, some say, and I have been known to concur, of the crime and thriller genres. Tosh! I can only apologise to all authors involved and own up: I simply haven't been paying attention. Not even to shorter offerings my by favourite authors. So: big thanks to Lee Child and publishers Bantam Press for putting me straight with ''No Middle Name'': a collection of short stories about my favourite latter-day, American-style, Robin Hood by the name of ''Jack Reacher''.
