Edgar Wallace 
Bones in London 

The new managing director of Schemes Ltd. has an elegant London office and a theatrically dressed assistant. However Bones, as he is better known, is bored. Luckily there is a slump in the shipping market and it is not long before Joe and Fred Pole pay Bones a visit. They are totally unprepared for Bones’ unnerving style of doing business, unprepared for his unique style of innocent and endearing mischief. (Goodreads)
