Old Broadbrim on the Trail of the Iron Frog

A locked room. A missing weapon. A letter that vanishes like smoke.

Old Broadbrim, the Quaker detective, is the sharpest mind in New York—and he knows it. When Percy Manson, a wealthy banker, turns up dead in his locked library with no weapon and no letter, the police are baffled. Old Broadbrim is not. He has a trail, a clue whispered by a strange clairvoyant child, and a target: a house near the river with a broken shutter.

He walks straight into a trap.

Dragged half-dead from the front steps by a demon noose, Old Broadbrim surfaces in a stone dungeon with nothing but a candle and a locked door—and he fights his way out anyway. What he finds in the dark corridor beneath that cursed house shakes him: a bundle of letters addressed to the dead banker, letters that carry a terrible secret someone is willing to kill to protect.

Now, a rival English detective circles the Manson widow. A skittish coachman runs for his life. A young woman clutches a secret she trusts only to Broadbrim. And somewhere in the shadows of New York's East Side, a cold-blooded killer watches the Quaker detective close in.

Old Broadbrim knows the letter holds the answer. He knows the Iron Frog is real. The only question is whether he finds it before it finds him first.
