I grabbed her by the arms and shook her. Her false teeth fell out and rolled across the carpet. [snip] I started into the parlour, but a thin man in shirtsleeves was in the way. I hit him and he went down. In the parlour the blonde who’d slugged me with the lamp began to scream. She thought I was coming for her. I went to the big radio in the corner. I picked it up, tearing out the plug, and tossed it across the room. It shattered against the wall. I kicked over a table with two lamps on it. I tore some of the fabric off a davenport. I threw a chair at a big oil painting over the fireplace. I took a metal stand lamp and bent it up like a pretzel. I pulled up the oriental rug and ripped it down the middle.
That’s going berserk like you mean it. We won’t bother with a long plot summary since you can find those all over the internet, but basically the protagonist is hired to spring a woman from a cult and finds himself neck deep in corpse worship, hidden treasure, police corruption, and sado-masochism. The book is reasonably well written, very hard boiled, and built around a set of unlikely characters—including a femme fatale known by all as “The Princess.” Great Pan published it in 1961, and it had an alternate cover which you also see here. It was re-issued several times after its debut—including by Popular Library as The Fifth Grave—which means it isn’t hard to find. We recommend you give it a read.
