This is always important – and particularly vital if you are investigating a theft or a murder.
Note that you’ll need a stiff upper lip if it’s a murder you’re dealing with – bodies and blood should be no barrier to truth and justice, but in practice, they are rather upsetting, especially to Hazel. However, you must simply swallow your fear and start hunting for clues.
Does anything seem out of place? Has anything been moved, documents rifled through or books searched? Could something be missing from the room, and if so has it left behind traces? Look for rings of dust where ornaments have sat or faded places on a wall where pictures were hung.
And if nothing is missing, has anything been left behind by the culprit? This might be an item of clothing, a cigarette butt, or even – if you’re very lucky - the murder weapon. Or perhaps something subtler – a strand of hair, a spot of blood, fingerprints, or footprints. More on prints later, as they’re utterly invaluable.
