Elevator of Doom [EPUB ebook] 
An Adventure of the Silencer

New York City, 1936: The Radcliffe, a luxury apartment building on Central Park West, is terrorised by a string of burglaries. The police suspect an insider, but there is no hard evidence, because the burglar comes and goes like a ghost.
At first glance, it seems like a simple enough job for Richard Blakemore, the masked crimefighter known only as the Silencer. Stake out the Radcliffe, nab the burglar and be back in time for dinner with Constance, his beautiful fiancée.
But even small-time criminals can fight back. And such a fight can quickly get out of hand, once Richard steps into the elevator of doom…
This is a novelette of 7600 words or approx. 22 print pages in the Silencer series, but may be read as a standalone.
