MOLLIE RALSTON – A newlywed who has inherited Monkswell Manor and has opened it as a guesthouse with her husband. A hospitable and warm, if slightly naive, hostess and cook.

GILES RALSTON – The more cautious proprietor of Monkswell Manor. Supportive of his wife, but less thrilled to run a guesthouse. A traditional gentleman who’s quick to judge his guests.

CHRISTOPHER WREN – A young architect with a flamboyant and often inappropriate sense of humor. His energetic conversation can appear both lighthearted and sinister.

MRS. BOYLE – A retiree whose acerbic tone makes her a challenging guest. Strong-willed and uncompromising, with high expectations. Pleased only when expressing disappointment.

MAJOR METCALF – An affable guest who is willing to help his hosts cope with the consequences of the snowstorm. Retired from the army, steady and calm in the face of conflict.

MISS CASEWELL – A modern and somewhat aloof young woman travelling on business. Unwilling to discuss private matters and disinterested in the opinion of her fellow guests.

MR. PARAVICINI – A roguish gentleman who is not forthcoming about his reasons for being there. Delights in the guests’ uncertainty and pays particular attention to his hostess, Mollie.

DETECTIVE SGT. TROTTER – The young detective assigned to reach Monkswell Manor and report on the situation as it unfolds. Determined and authoritative in his pursuit of the truth.
