The Logder' tells the story of Mr. and Mrs. Bunting, the owners of a failing lodging in London. When a guest called Mr. Sleuth arrived after a long time, the couple saw in him their chance to recover their business. But when several murders happen in the surrounding neighborhoods, the Buntings slowly begin to doubt their lodger might be the one responsible for them. This murder mystery is based on the Whitechapel murders of 1888, committed by Jack the Ripper.
